Answers & Solutions:
1) Answer (C)
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 = $02:27\dfrac{3}{11}$
2) Answer (D)
A>B>C and C<D<E and A<E,
So, C is the youngest and E is the oldest.
3) Answer (A)
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.
4) Answer (B)
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.
5) Answer (B)
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 $Y=p^2=36$
6) Answer (D)
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, $\frac{B}{A} = \frac{24}{25} = 0.96$
7) Answer (C)
Volume of cake = vol.of bread + vol.of chocolate
(20)(14)(8) = vol.of bread + 880
2240 = vol.of bread + 880
Vol.of bread = 1360
So the answer is option C.
8) Answer (B)
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.
9) Answer (A)
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.
10) Answer (B)
MUTE is the only meaningful word that can be formed using the given alphabets.
Hence, option B is the answer.
11) Answer (A)
(9-6)*2 = 6
(7-2)*4 = 20
(11-4)*3 = 21
Hence, option A is the right choice.
12) Answer (B)
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.
13) Answer (C)
14) Answer (C)
15) Answer (B)
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.
