Rama Rao was facing crisis of earning money. He was disappointed but he worried less about his family because now he was thinking intensely about the answers to the crossword puzzles in ‘The Captain’.

रामा राव धन कमाने का संकट महसूस कर रहा था। वह निराश था लेकिन वह अपने परिवार के बारे में कम चिन्तित रहने लगा क्योंकि अब वह तीव्रता से ‘द कैप्टिन’ में दी गयी शब्द-पहेलियों के उत्तर सोचने में व्यस्त रहता था।

Rama Rao came across “The Captain’, a journal of four pages. It had crossword puzzles and offered every week a prize of four thousand rupees for a correct answer.

रामा राव को ‘द कैप्टिन’ नामक पत्रिका मिली जो चार पन्ने की होती थी। इसमें शब्द-पहेलियाँ होती थीं तथा हर सप्ताह यह सही उत्तर के लिए चार हजार रुपये के पुरस्कार का प्रस्ताव देती थी।

They expected to know if he had returned with the offer of a job.

वे जानना चाहते थे कि क्या वह कोई नौकरी का प्रस्ताव लेकर आया था।

Formerly Rama Rao worked in a gramophone company. It suddenly collapsed. He was jobless. The only source of income for Rama Rao was the small rent they were getting for their house in the Extension.

पूर्व में रामाराव एक ग्रामोफोन कम्पनी में काम करता था। यह कम्पनी अचानक ठप्प हो गई। वह बेरोजगार हो गया। रामा राव के लिए आय का एकमात्र साधन छोटा-सा किराया था जो वे अपने एक्सटेंशन स्थित बंगले के बदले प्राप्त कर रहे थे।

Rama Rao’s wife and children were perfectly happy at the bungalow in the Extension. Now she spent all her time in the kitchen. The children had now no friends and played only in the backyard of the house.

रामा राव की पत्नी एवं बच्चे एक्सटेंशन वाले बंगले में पूरी तरह प्रसन्न थे। अब वह अपना सारा समय रसोई-घर में बिताती थी। अब बच्चों के कोई मित्र नहीं थे और वे मकान के पिछवाड़े में खेला करते थे।

The children had a bad time in the new house. They had no friends to play with and only the backyard of the house to play in. Their clothes had tears and frays.

नये घर में बच्चों का समय बुरा बीतता था। साथ खेलने हेतु मित्र नहीं थे तथा खेलने के स्थान के रूप में केवल घर का पिछवाड़ा मात्र था। उनके कपड़े फटने एवं तार-तार होने लगे थे।

Rama Rao decided to go to Madras to see if he could find some profitable work there..

रामा राव ने मद्रास जाने का निश्चय इसलिए किया क्योंकि वह देखना चाहता था कि वह वहाँ कोई लाभप्रद कार्य हूँढ़ सकता था, अथवा नहीं।

One day the good journal announced a special offer of eight thousand rupees. It excited Rama Rao’s vision of a future tenfold. He studied the puzzle. There were only four doubtful corners in it and he might have to send in at least four entries.

एक दिन उस भली पत्रिका ने आठ हजार का विशेष प्रस्ताव घोषित किया। इसने रामाराव के भविष्य के स्वप्न को दस गुना रोमांचित कर दिया। उसने पहेंली का अध्ययन किया। इसमें केवल चार सन्देहास्पद कोने थे । और उसे कम से कम चार प्रविष्टियाँ भेजनी पड़ सकती थीं।

She took a few measures to save money. She sent away the cook and the servant, sent her children to a pre primary school. And let out their bungalow and moved to a very small house behind the market.

उसने बचत के कुछ तरीके काम में लिए। उसने रसोइए तथा नौकर को हटा दिया, बच्चों को प्री-प्राइमरी स्कूल में भेज दिया तथा अपने बंगले को किराये पर उठा दिया और बाजार के पीछे एक छोटे घर में रहने चले गये।

Rama Rao’s wife withdraws her children from expensive nursery school because she is trying some measures of economy

रामा राव की पत्नी, अपने बच्चों को महँगी नर्सरी स्कूल से निकाल लेती है क्योंकि वह बचत के कुछ तरीके काम में ले रही है।

Ramarao is a hardworking man. He keeps his wife and children in good comfort. After getting unemployed, he tries his best to find a new job but he fails. He is a plain speaking person. When he fails to get any employment, he tries to win prizes in crossword puzzles. he also fails in it. Then he decides to commit suicide. He changes his mind when the train is late and decides to start a new life.

रामा राव एक मेहनती आदमी है। वह अपनी पत्नी एवं बच्चों को आराम में रखता है। बेरोजगार होने के बाद वह नया काम ढूंढने की बहुत कोशिश करता है किन्तु प्राप्त नहीं कर पाता है। वह अपनी बात कहने में व्यावहारिक है। किसी अन्य कार्य को प्राप्त करने में असफल होने पर वह वर्ग पहेलियों द्वारा इनाम जीतने की कोशिश करता है। इसमें भी असफल रहने पर वह आत्महत्या करने का निश्चय करता है। रेल में विलम्ब होने के कारण उसका मानस बदलता है तथा वह जीवन को नये सिरे से शुरू करने का निश्चय करता है।

1. False

2. False

3. True

4. True

5. True

It is given that

l + b + h = 19cm ……. (1)

Diagonal = √ (l² + b² + h²) = 11cm…….. (2)

Squaring on both sides of equation (1)

(l + b + h) ² = 19²

So we get

(l² + b² + h²) + 2 (lb + bh + hl) = 361 …….. (3)

Squaring on both sides of equation (2)

l² + b² + h² = 11² = 121 ……. (4)

Substituting equation (4) in (3)

121 + 2 (lb + bh + hl) = 361

So we get

2 (lb + bh + hl) = 361 – 121

By subtraction

2 (lb + bh + hl) = 240 cm²

Therefore, the surface area of the cuboid = 240 cm².

It is given that

Surface area of cuboid = 758 cm²

The dimensions of cuboid are

Length = 14cm

Breadth = 11cm

Consider h as the height of cuboid

We know that

Surface area of cuboid = 2 (lb + bh + lh)

By substituting the values

758 = 2 (14 × 11 + 11 × h + 14 × h)

On further calculation

758 = 2 (154 + 11h + 14h)

So we get

758 = 2 (154 + 25h)

By multiplication

758 = 308 + 50h

It can be written as

50h = 758 – 308

By subtraction

50h = 450

By division

h = 9cm

Therefore, the height of cuboid is 9cm.

The dimensions of classroom are

Length = 10m

Breadth = 6.4m

Height = 5m

It is given that the floor area for each student = 1.6m²

So the number of students = area of room/floor area for each student

By substituting the values

Number of students = (10 × 6.4)/1.6

So we get

Number of students = 40

So the air required by each student = Volume of room/ number of students

We know that Volume of room = l × b × h

By substituting the values

Volume of room = 10 × 6.4 × 5 = 320 m³

So we get

Air required by each student = 320/40 = 8m³

Therefore, the number of students that can be accommodated in the room is 40 and the air required by each student is 8m³.

After having failed to win the special offer crossword puzzle, Rama Rao decided to end his life on the railway line. He lay across the lines for a long time waiting for the train from Trichinopally. But it did not come. Going to the station, he found out that the way was blocked on account of derailment of a goods train. Thus his life was saved. He believed God had shown him mercy.

स्पेशल ऑफर शब्द-पहेली जीत पाने में असफल रहने के बाद रामा राव ने रेल की पटरी पर जीवन का अन्त करने का निश्चय किया वह रेल लाइन पर काफी समय तक लेटा रहा और त्रिचिनोपल्ली से आने वाली ट्रेन का इन्तजार करने लगा। लेकिन यह नहीं आयी। स्टेशन जाकर उसने पाया कि एक मालगाड़ी के पटरी से उतर जाने के कारण रास्ता बन्द हो गया। इस प्रकार उसका जीवन बच गया था। उसने मान लिया कि ईश्वर ने उस पर रहम किया था।

The train gets late because a goods train has derailed three stations off and the way is blocked.

रेलगाड़ी विलम्ब हो जाती है क्योंकि तीन स्टेशन दूर एक मालगाड़ी पटरी से उतर गई है और रास्ता रुक गया है।

When Rama Rao’s wife informs him that the tenants are ready to buy their bungalow, he is happy because they are ready to offer good cash for it immediately. Now he may be free from sufferings.

जब रामा राव की पत्नी उसे सूचित करती है कि किरायेदार उनके बंगले को खरीदना चाहते हैं, वह प्रसन्न हो जाता है क्योंकि वे इसके लिए तुरन्त अच्छी कीमत नकदी में देने के लिए तैयार हैं। अब वह सभी दुःखों से मुक्त हो सकता है।

Every supply has a capacity to bear a maximum load, i.e., the power that can be supplied has a limit. Sometimes, the number of appliances which are switched on at the same time have power more than the capacity of the line. This is called overloading. In this situation, wires of the supply get heated due to extremely large current flowing through them and the circuit may catch fire. To avoid this fire, we use an electric fuse in the circuit.

Whenever live and neutral wires come in contact with each other, the incident is called short circuiting. In this case, resistance of a circuit decreases to a very small value. The decreasing of resistance increases the current. Due to this increased current, the wires get heated. This extreme heat may cause fire in the building.

A.C. voltage can be stepped up and transmitted over long distances without much loss of energy.

(i) When north pole is pushed into the coil, a momentary deflection is observed in the galvanometer. This deflection indicates that a momentary current is produced in the coil. The direction of current in the coil is anticlockwise.

(ii) When the magnet is held at rest, there is no deflection in the galvanometer. It indicates that no current is produced in the coil in this use.
(iii) In pulling the magnet out of the coil, a deflection in opposite direction is observed. It indicates that the current produced in the coil is in opposite direction.

(i) Due to the force exerted by the magnet within its magnetic field. 

(ii) The lines represent magnetic field lines. 

(iii) Crowding of iron filings at the ends of the magnet indicates that the magnetic field is strongest near the poles of the magnet.

(iv) The strength of the magnetic field is indicated by the closeness of the field lines. Closer the lines, more will be the strength and farther the lines, lesser will be the field strength.

Two magnetic field lines do not intersect each other due to the fact that the resultant force on a north pole at any point can be only in one direction. But if the two magnetic lines get intersect one another, this means that resultant force on a north pole placed at the point of interection will be along two directions, which is not possible.

The space surrounding a magnet in which magnetic force is exerted, is called a magnetic field. The direction of magnetic field lines at a place can be determined by using a compass needle. A compass needle placed near a magnet gets deflected due to the magnetic force exerted by the magnet. The north end of the needle of the compass indicates the direction of magnetic field at the point where it is placed.

The magnetic field lines of force are the lines drawn in a magnetic field along which a hypothetical north magnetic pole would move if it is free to do so. The direction of a magnetic field at a point is the direction of the resultant force acting on a hypothetical north pole placed at that point.The tangent at any point on the magnetic field line gives the direction of magnetic field at that point. the direction of the magnetic field at a point can be found by placing a small magnetic compass at that point. L he north end of the needle indicates the direction of the field.
Two important properties of the magnetic lines of force are:
(i) The magnetic lines of force start from north pole and terminate atsouth pole. Inside the magnet, they travel from south pole to north pole. Thus, they are closed curves.
(ii) They do not intersect each other because at the point of intersection there will be two directions. ofsame magnetic field which is impossible.

(B) is the correct option.

The correct choice is (C). The total number of injective mappings from the set containing 3 elements into the set containing 4 elements is ⁴P₃ = 4! = 24.

(C) is the correct choice.

(4) 6 and 5.

The Pre images of 3 are 6 and 5

(A) is the correct choice.

(C) is the correct choice since for f ^–1 ( 17 ) = x ⇒ f (x) = 17 or x² + 1 = 17

⇒ x = ± 4 or f ^–1 ( 17 ) = {4, – 4} and for f ^–1 (–3) = x ⇒ f (x) = – 3 ⇒ x² + 1

= – 3 ⇒ x² = – 4 and hence f ^–1 (– 3) = φ.

Intensity of gravitational field has the same dimensional formula as that of acceleration.

Given ratio = 7: 8

Let the ratio of consequent and antecedent 7x: 8x

Consequent = 40

8x = 40

x = 40/8

x = 5

Antecedent = 7x = 7 × 5 = 35

Antecedent = 3, Consequent = 5.

Given: base = 24 cm, corresponding height = 14.5 cm

Area of a triangle = \(\frac{1}{2}\)x base x corresponding height

= \(\frac{1}{2}\times24\times14.5\)

= 174 cm²

Given:

Base of triangle = 24 cm

Height = 14.5 cm

Area of a triangle = 1/2 x Base X Height

= 1/2 x 24 x 14.5

= 174

Area of a triangle is 174 cm².

 Let a, b and c be the sides of a triangle.

Apply Heron's Formula to find the area of triangle.

Area = \(\sqrt{S(S-a)(S-b)(S-c)}\)

Where S = \(\frac{a + b + c}{2}\)

Here a = 18 cm, b = 24 cm, c = 30 cm

Now,

S = 1/2(18+24+30) = 36

Area = √(36(36-18)(36-24)(36-30))

= √(36 × 18× 12 × 6)

= 216

Area is 216 cm²

From given, Length of smallest side = 18 cm

Area of a triangle = 1/2 × Base × Height

216 = 1/2 x 18 x height

Height = 24

Therefore, the height corresponding to the smallest side is 24 cm.

Let a, b and c be the sides of a triangle.

Apply Heron's Formula to find the area of triangle.

Area = \(\sqrt{S(S-a)(S-b)(S-c)}\)

Where S = \(\frac{a + b + c}{2}\)

Here a = 42 cm, b = 34 cm and c = 20 cm

S = (42 +34 +20)/2 = 48

Area = √(48(48-42)(48-34)(48-20))

= √(48 x 6 x 14 x 28)

= 336

Area of triangle is 336 cm².

Clearly,

Length of longest side = 42 cm

Also we know, Area of a triangle = 1/2 × Base × Height

336 = 1/2 × 42 × Height

336 = 21 x Height

or Height = 16

The height corresponding to the longest side is 16 cm.

Correct option is A) 58

Answer : (a) 1650

Let the first term of the A.P. be a and let the common difference be d.

Then, t₁₂ + t₂₂ = 100 

⇒ (a + 11d) + (a + 21d) = 100 

⇒ 2a + 32d = 100 ...(i) 

Now sum of first 33 terms of the A.P

= \(\frac{33}{2}\) (2a + 32d)  \(\big(\because S_n = \frac{n}{2}(2a+(n-1)d\big)\) 

= \(\frac{33}{2}\) × 100  (From (i)) 

= 1650.

Given,

m = 50 kg

g = 9.8 m/s²

The force does he need to lift the load.

F = mg

F = 50 x 9.8

F = 490 N

The person will need to apply this amount of force, in opposite direction.

G = specific gravity,

P_A = pressure at A,

P_B = Pressure at B

Pressure at any point is the same horizontal line x – x should be same.

Hence, pressure at C in left column = pressure at D in right column.

Pressure at C

= (2 × 1000 × g × 2) + (1 × 1000 × g × 4) + P_A …..(1)

pressure at D

= (4 × 1000 × g × 2) + P_B ……(2)

Equating (1) and (2),

8000 g + P_A = 8000 g + P_B

P_A – P_B = 0

(d) All of the above

(c) Related to monetary policy

(a) Monetary Policya

(c) Both (a) and (b)

(c) Both (a) and (b)
