What is the number that is always a factor of the sum of a 2-digit number and a number obtained by interchanging the digits of the number?1. 52. 33. 114. 9

Answer» Correct Answer - Option 3 : 11

Calculation:

Let two digit number be 10a + b and number after interchanging digits be 10b + a.

⇒ 10a + b + 10b + a = 11a + 11b = 11(a + b)

∴ From above, 11 is always a factor of their sum.

B) If \( y=\sin x \cdot \cos x \), show that \( \frac{d y}{d x}=\cos 2 x \)

Answer»

y=sinx.cosx by differentiation
dy/dx=cosx.cosx-sinx.sinx                                   diff(U.V)=(diff U).V+U.(diff V)
         =cos2x-sin2x
         =cos2x (by formula)                                       diff (sinx)=cosx
                                                                               diff (cosx)=-sinx
so that if y=sinx.cosx 
                                      dy/dx=cos2x

The ratio between the two digit number and two digit number obtained by interchanging digits is 9 : 2. The sum of two digits of number is 9. Find the two digit number.1. 272. 363. 724. 185. 81

Answer» Correct Answer - Option 5 : 81

Given:

The ratio between the two digit number and two digit number obtained by

interchanging digits is 9 : 2

Calculation:

Let two digit number be 10a + b.

The two digit number obtained after reversing it's digit = 10b + a

⇒ (10a + b) : (10b + a) = 9 : 2

⇒ 20a + 2b = 90b + 9a

⇒ 11a = 88b

⇒ a = 8b

Then,

⇒ a + b = 9

Solving,

a = 8 and b = 1

 Two digit number = 10a + b = 81

Therefore the correct answer is 81.

At what time after 7:00 pm will the hands of the clock be opposite to each other?

Answer»

Just at 7.00pm the hour hand is at 7 and minute hand is at 12.

Each minute division makes 6 at the center. So at 7.00 pm a reflex angle of 210 will be formed between hour hand and minute hand because the hour hand will be at 35 minute divisions ahead of minute hand.

Let x minute after 7.00pm the hands of the clock will be opposite to each other.Then the angle between the hands will be 180

We know hour hand rotates 360 in 12hr or 720 minutes

So in x minute the hour hand will increase the reflex angle by 360x720=(x/2)

In this x minute the minute hand will decrease the reflex angle by (6x) .

Hence

210+(x/2)−(6x)=180

⇒x=(60/11) minute

So at 7 past 55/11minute the hands will become opposite to each other.

In which year in the future is Halley's Comet estimated to be seen in the solar system?1. 20502. 20703. 20614. 2056

Answer» Correct Answer - Option 3 : 2061

The correct answer is 2061.

  • Comets are considered to come from a vast reservoir, the Oort cloud, orbiting the Sun at distances of 20,000–50,000 AU or more and containing trillions of icy objects which have the potential to become active comets. 
  • Halley’s Comet is the best known of these periodic comets; its next return into the inner solar system is predicted for 2061.
  • Many short-period comets are thought to come from the Kuiper belt, a region lying mainly between 30 AU and 50 AU from the Sun.
  • Smaller than the observed asteroids and comets are the meteoroids, lumps of stony or metallic material believed to be mostly fragments of asteroids.
  • Pluto, Eris, and Ceres, the latter being the largest member of the asteroid belt.
  • Two other Kuiper belt objects, Makemake and Haumea, were also designated as dwarf planets.

If A is non- singular martix and `(A +l)(A-l) = 0` then `A A^(-1)` = …….A. 2AB. 0C. lD. 3l

Answer» Correct Answer - A
We have , A is non-singular matrix
`therefore" "|A| = 0`
and `(A+l) (A -l) = 0`
`rArr " "A^(2) - l^(2) = 0`
`rArr " "A^(2) = l^(2) = l`
`rArr " ""A.A = l rArr A^(-1)A`
`therefore " "A + A^(-1) = A+A =2A`

If `int(cosx-sinx)/(8-sin2x)dx=(1)/(p)log[(3+sinx+cosx)/(3-sinx-cosx)]+c`, then p= . . . .A. 6B. 1C. 3D. 12

Answer» Correct Answer - A
We have ,
`int (cos x - sinx)/(8- sin 2x) = (1)/(log) [(3sin x + cos x)/(3-sin x - cos x)] + c`
Now `int(cos x -sinx)/(8-sin 2x)dx`
` int = (cos x - sinx)/(9-(1+(2 sin x cos x)) dx`
`int(cos x-sinx)/((3)^(2) -(cos x+sinx)^(2))dx`
`=int(cos x - sinx)/((3)^(2) -(cos x + sinx)^(2))dx`
put cos x + sin t
`(-sin x+ cosx) dx = dt`
` = int(dt)/((3)^(2) -(t)^(2)) = (1)/(2(3)) log|(3+t)/(3-t)|+C`
` = (1)/(6) log|(3+sin x+cosx)/(3-sin - cos x)| +C`
`therefore` p = 6

If A,B,C and D are {3,7,4),(5,-2,-3),(-4,5,6) and (1,2,3) respectively, then the value of the parallelopiped with AB, AC and AD as the co-terminus edges, is . . . Cubic units.A. 91B. 94C. 92D. 93

Answer» Correct Answer - C
We have
`AB = (5 -3)hati +(-2 - 7)hatj + (3 -4)hatk`
` = 2hati - 9hatj - hatk`
`AC = (-4 - 3)hati + (5- 7) hatj + (6 - 4)hatk`
`= -7 hati - 2hatj + 2hatk`
and `AD = (1-2)hati + (2 - 7)hatj + (3 -4) hatk`
`= -2hati - 5hatj - hatk`
`therefore ` Volume of the parallelopiped with AB, AC and AD on the co - terminus edges
`= |[AB AC AD]|= |{:(,2,-9,-1),(,-7,-2,-1),(,-2,-5,-1):}|`
` |2 (2+10) + 9(7+4) - 1(35-4)|`
`=|2(12)+9(11) -1(31)|`
`=|(24+99-31)|`
`= |92|` = 92 cubic units .

If `(-sqrt(2),sqrt2)` are cartesian co-ordinates off the point, then its polar co-ordinates are . . .A. `(1,( 4pi)/(3))`B. `(2,(3pi)/(4))`C. `(3,(7pi)/(4))`D. `(4,(5pi)/(4))`

Answer» Correct Answer - B
We have `r cos theta = - sqrt(2)` and `r sin theta = sqrt(2)`
`therefore r^(2) cos ^(2) theta + r^(2) sin theta = 2 + 2 = 4`
`rArr^(2) )(cos ^(2) theta + sin^(2) theta) = 4`
` rArr r = pm and theta = tan^(-1)((sqrt(2))/(-sqrt(2)))`
`theta = tan^(-1) (-1)rArr theta = (3pi)/(4)`
`therefore ` Requrired polar co-ordinates is `( r , theta)`
` =(2,(3pi)/(4))`

Read the following text and answer question 'Saarthi', the name has been associated with the manufacturing and sale of Fashion products since 1960, when Kapil Saarthi opened his first retail fashion clothing outlet in Ahmedabad. Sarthi Cosmetics was incorporated in India in 1940, and became a member of the S & M family of companies in 1959. Sarthi Perfumes began operations in Gujarat in an existing administrative S&M facility in 1985. An important difference between S&M and most other companies is that instead of operating as one large corporation it operates as 180 smaller companies each focused on a specific product and area, implying selective dispersal of authority, recognising the decision makers need four autonomy, as decision making authority is pushed down the chain of command. It enables the company to maintain short lines of communication with customers and employees, and accelerate the development of talent.1. Identify the philosophy that is being followed by S&M through which it is dividing the decision making responsibilities among hierarchical levels. (a) Delegation of authority (b) Decentralization of authority; (c) Division of work (d) Span of management.2. ‘Why is there, need to apply the philosophy being followed by S&M, with caution? (a) As it can cause a delay in communication (b) As it can cause disintegration of the organisation (c) As it can increase the workload of the top management (d) As it can reduce the chances of growth of the firm.3. The application of the philosophy discussed above can foster a sense of competition amongst the departments, which in turn will help the firm in the following manner: (a) Facilitates growth (b) Better control (c) Relief to top management (d) Quick decision making4. Quote the line from above which highlights the importance of the philosophy towards providing management education to employees. (a) “Maintain short lines of communication (b) ‘Accelerate the development of talent’ (c) ‘selective dispersal of authority; (d) ‘Recognises decision makers need for autonomy’5. As “The decision making authority is pushed down the chain of command” at S&M enterprises, it provides the benefit of quick decision making to the organisation because: (a) There is no requirement for approval from many levels (b) Organisation is able to generate more returns (c) There are innovative performance systems (d) It's a means of management education6. The philosophy being followed by S&M is not followed by most other companies. This tells us that the philosophy is :(a) Optional (b) Compulsory (c) Limited to superior and his subordinate (d) Merely done to lessen the burden of the manager

Answer»

1. (b) Decentralization of authority;

2. (b) As it can cause disintegration of the organisation

3. (a) Facilitates growth

4. (b) ‘Accelerate the development of talent’

5. (a) There is no requirement for approval from many levels

A body dropped from the top of tower falls through 200 m during last 5 seconds of its fall. Find height of the tower.

Answer»

In case of free fall displacement of the motion 

\(S = \frac 12 gt^2\)

nth four second

(n - 5)th = tn-5

given (tn - tn-5) = 5

Displacement in last five second 

\(S_{n , n-5} = \frac 12 g (t_n - t_{n -5})^2\)

\(200 = \frac 12 \times 10\times (t_n - t_{n - 5})^2\)

\(40 = (t_n - t_{n - 5}) (t_n + t_{n - 5})\)

\(40 = 5 (t_n + t_{n - 5})\)

\(8 = t_n + t_{n - 5}\)

Solving equation (1) and (2)

\(\begin{array}{r}t_n + t_{n-5} = 8\\t_n - t_{n - 5} = 5\\\hline 2t_n= 13\end{array}\)

\(t_n = \frac{13}2\)

\(t_n = 6.5 \) sec

\(t_{n-5} = 5 + 6.5\)

\(t_{n-5} = 11.5\) 

Height of the building

\(S = \frac 12 gt^2\)

\(S = \frac 12 \times 10\times (6.5)^2\)

\(S = 5\times 42.25\)

\(S = 211.25\)
