Instructions

Five friends A,B,C,D and E are comparing their ages.
C is younger than only one person. The number of people younger than A is same as the number of people older than A. B is younger than E but older than D.

Question 12: Who is the youngest person in the group?

a) C

b) D

c) A

d) B

Question 13: Curd contains mainly ……….. acid.

a) Benzoic

b) Kalibangan

c) Surkotoda

d) Nalini

Question 15: Eleven years ago, the sum of the ages of Ram and his younger brother was 36. 11 years from now, the ratio of their ages will be 11:9. What is the present age of Ram’s brother?

a) 36 years

b) 25 years

c) 27 years

d) 23 years

Angle between two hands $= \dfrac{11}{2}M – 30H$ where H is hours and M is Minutes
Here, H = 2 and Angle = $90^\circ$
$90^\circ = \dfrac{11}{2}M – 30\times2$
⇒ $\dfrac{11}{2}M = 150$
⇒ $M = \dfrac{300}{11} = 27\dfrac{3}{11}$
Hence, the required time = $02:27\dfrac{3}{11}$

A>B>C and C<D<E and A<E,

So, C is the youngest and E is the oldest.

Catch means to capture or get something and here the person didn’t get what was being said.Receive is incorrect because nothing was given here to be received.Thus, option A is correct.

A Stretcher is a device like a cot which is used for carrying sick people. Thus option B has the word which is correctly spelt.

Let the value of $\sqrt{Y} = p$. Note that $p$ is positive.
Therefore, $p^2 – p = 30$
Or, $p^2 – p – 30 = 0$
Therefore, $p^2 – 6p + 5p – 30 = 0$
Therfore, $(p-6)(p+5)=0$
Hence, $p=6$ or $p=-5$
But as $p$ is positive, it implies that $p=6$ and $Y=p^2=36$

We know that $\frac{4}{5} \times A = \frac{5}{6} \times B$
Therefore, $\frac{4 \times 6}{5 \times 5} = \frac{B}{A}$
Therefore, $\frac{B}{A} = \frac{24}{25} = 0.96$

Volume of cake = vol.of bread + vol.of chocolate

(20)(14)(8) = vol.of bread + 880

2240 = vol.of bread + 880

So the answer is option C.

Let a, a are the adjacent sides of the isosceles triangle,

$a^2+a^2 = (6\sqrt2)^2$

$2a^2 = 72$

$a = 6$

Area of triangle = $\frac{1}{2}\times 6 \times 6$ = $18sq.m$

So the answer is option B.

Since Mumbai is the costliest city, Delhi will be comparatively cheaper. Thus, conclusion I follows.
Further, we cannot conclude which city is cheaper to live. Thus, conclusion II does not follow.
Hence, option A is the right answer.

MUTE is the only meaningful word that can be formed using the given alphabets.
Hence, option B is the answer.

(9-6)*2 = 6
(7-2)*4 = 20
(11-4)*3 = 21
Hence, option A is the right choice.

Arranging A,B,C,D and E in increasing order of their ages from right to left.

C is younger than only one person.
__ C __ __ __

The number of people younger than A is same as the number of people older than A.
⇒ __ C A __ __

B is younger than E but older than D.
⇒ E C A B D
Hence, D is the youngest person.

Let us assume Ram and his brother are ‘x’ and ‘y’ years. (x >y)

We know that, x-11+y-11 = 36

$\Rightarrow$ x+y = 58 … (1)

After 11 years

$\frac{x+11}{y+11} = \frac{11}{9}$

$\Rightarrow$ 9x + 99 = 11y + 121

$\Rightarrow$ 9x – 11y = 22 … (2)

Solving both the equation, we get,

$\Rightarrow$ 11x + 11y = 638

$\Rightarrow$ 9x + 11x = 638 + 22

$\Rightarrow$ x = 33; y = 58 – 33 = 25

Hence we can say that Ram’s brother is 25 years old.
