Answer the following questions according to the text.In order to make the first clock, man had to first divide the day into hours and minutes. The Babylonians were the first to divide the hour into 60 minutes and the minute into 60 seconds. The Egyptians created shadow clocks which later became sundials. Around 100 B.C. the first hourglass was used. These were usually timed for one hour. The Greeks and Romans later used water clocks which had been developed by the Chinese and were called clepsydras. The first mechanical clocks were developed in Europe in the 1300’s. These were improved and in 1656 a Dutchman designed the first pendulum clock, which was more accurate than the other clocks of the time. After World War 11 the atomic clock was developed and is still the world’s most accurate clock. The quartz crystal clocks and watches that were developed in the 1960’s and 70’s are also extremely accurate, second in accuracy to only the atomic clock. 1.

A square base is sometimes referred to as a “preliminary” base or preliminary fold.Here is a 20 cm × 20 cm square. Gurmeet wants to first cut the squares of integral length from the corners and by folding the flaps along the sides.(a) How many squares of dimensions 2cm × 2cm can Gurmeet make? i.5 ii.7 iii.10 iv.20 (b) What is the max radius of hemisphere which can be cut out from the square ? i.5cm ii.10cm iii.12cm iv.7cm (c) What is the area of remaining left out paper if cone of radius 1 cm and height 10 cm is cut out from the square? i.365.303 cm2 ii.371.583 cm2 iii.300 cm2iv.360 cm2 (d) How many folds are possible if final dimension of fold has to be 4cm × 4cm? i.25 ii.20 iii.15 iv.30 (e) How many triangles can be cut out, each of area 80 cm2? i.6 ii.3 iii.8 iv.5

Answer»

Dimension of square (given paper) is 20cm×20cm. 

Therefore, 

Area of given paper is 400 cm2

(a) Option : (iii) 

Gurmeet want to make squares of 2cm × 2cm from the given paper (square of 20 cm)

Therefore, 

The area of required square is 4cm2 

Hence, 

Total number of required squares = \(\frac{area\, given\,square}{ area\,of\,required\,squre}\) 

= \(\frac{400}{40}\) = 10. 

Hence,

10 squares of dimensions 2cm × 2cm can Gurmeet make.

Hence,

Option (iii) is correct.

(b) Option : (ii) 

The maximum diameter of hemisphere which can be cut out from the square = Side length of square = 20 cm. 

Hence,

Maximum radius of hemisphere = \(\frac{20}{2}\) 

= 10cm. 

Hence, 

Option (ii) is correct.

(c) Option : (ii)  

Radius of cone is r = 1 cm 

And height of the cone is h = 10cm.

The slant height of the cone is l = \(\sqrt{r^2+h^2}\) 

\(\sqrt{1^2+10^2}\) 

\(\sqrt{101}\) cm.

Total surface area of the cone = πr(r+l)

= 3.14 ×1(1+√101) 

= 3.14 × (1+10.05) 

= 3.14(11.05) 

= 34.697 cm2.

Area of base of the cone = πr2 

= 3.14 × 12

= 3.14 cm2.

Remaining area = Area of square –Total surface area of cone +2×Area of base of the cone

= 400 – 34.697 + 2×3.14 cm2

= 365.303 + 6.28 

= 371.583 cm2.

Hence, 

Option (ii) is correct.

(d) Option : (i)

Area of square of side length 4 cm 

= 42 = 16 cm2

Hence,

Total square of 4 cm = \(\frac{Area\,of\,square\,of side\,length\,20\,cm}{Area\,of\,square\,of\,side\,length\,4\,cm}\) 

\(\frac{400}{16}\)

= 25.

Hence,

Option (i) is correct.

(e) Option : (iv)

Given,

Area of triangle = 80 cm2

Total number of such triangle = \(\frac{Area\,of\,given\,paper}{ Area\,of\,one\,triangle}\)

= \(\frac{400}{80}\)

= 5. 

Hence, 

5 triangles can be cut out such that each triangle is having area 80 cm2

Hence,

Option (iv) is correct.

The product of the ages of Sagun and Srishti is 240. If twice the age of Srishti is more than Sagun's age by 4 years, then what is Srishti's age?1. 152. 123. 104. 20

Answer» Correct Answer - Option 2 : 12

Calculation:

Let the present age of Sagun and Srishti be x and y years respectively

Now, A/Q

xy = 240      ----(1)

And, 2y – x = 4      

⇒ x = 2y – 4      ----(2)

From eq (1) and eq (2),

(2y – 4)y = 240 

⇒ (y – 2)y = 120

⇒ y2 – 2y – 120 = 0

⇒ y2 – 12y + 10y – 120 = 0

⇒ y(y – 12) + 10(y – 12) = 0

⇒ (y – 12)(y + 10) = 0

y = 12 and y = -10

Age can not be in negative so y = -10 is neglected

∴ The present age of the Shristi is 12 years
