Question : Directions: In the following question a series is given, with one number missing. Choose the correct alternative from the given ones that will complete the series. 11, 13, 17, 19, 23, 25, ?
Option 1: 25
Option 2: 27
Option 3: 29
Option 4: 31
Correct Answer: 29
Solution : Given: 11, 13, 17, 19, 23, 25, ?
Add 2 and 4 alternatively to the terms of the series – 11 + 2 = 13; 13 + 4 = 17; 17 + 2 = 19; 19 + 4 = 23; 23 + 2 = 25;
Question : What is the value of $\frac{\cos 37^{\circ}}{\sin 53^{\circ}}?$
Option 1: $ \frac{1}{2} $
Option 2: $\frac{1}{\sqrt{2}}$
Option 3: $0$
Option 4: $1$
Correct Answer: $1$
Solution : $\frac{\cos 37^{\circ}}{\sin 53^{\circ}}$ $=\frac{\cos 37^{\circ}}{\sin (90^{\circ}-37^{\circ})}$ $=\frac{\cos 37^{\circ}}{\cos 37^{\circ}}$ $=1$ Hence, the correct answer is $1$.
Question : Select the most appropriate collocating word to fill in the blank.
Mentally strong people do not ________ to suicide over trivial issues.
Option 1: make up
Option 2: give in
Option 3: conceive on
Option 4: fall in

Question : If A's income is 60% less than B's income, then B's income is what percentage more than that of A's income?
Option 1: 40%
Option 2: 150%
Option 3: 120%
Option 4: 80%
Correct Answer: 150%
Solution : Let the B's income = 100 Since A's income is 60% less than B's income A's income = 100 – 60 = 40 So, A's income is 60 more than B's income The required percentage = $\frac{60}{40}$ × 100 = 150% So, A's income is
Question : Directions: In the question, a part of the sentence is in bold. Below are given alternatives to the bold part at 1, 2 and 3 that may improve the sentence. Choose the correct alternative. In case no improvement is needed, your answer is (4).
We do not believe in a dual policy of the company.
(1) in this dual
(2) in these dual
(3) on these dual
(4) No Improvement
Option 1: 1
Option 2: 2
Option 3: 3
Option 4: 4
Correct Answer: 1
Solution : The correct improvement for the sentence is: in this dual
Explanation: This option suggests replacing "in a dual" with "in this dual." "We do not believe in this dual policy of the company" provides a more specific and clear reference to the policy being discussed.
Question : A car starts from point A towards point B, travelling at the speed of 20 km/hr. $1\frac{1}{2}$ hours later, another car starts from the point and travels at the speed of 30 km/hr and reaches $2\frac{1}{2}$ hours before the first car. Find the distance between A and B.
Option 1: 300 km
Option 2: 240 km
Option 3: 260 km
Option 4: 280 km
Correct Answer: 240 km
Solution : Let the time taken by the first car to reach point B be $t$ hours. The time taken by the second car to reach point B = $t - 1\frac{1}{2} - 2\frac{1}{2} = t - 4$ hours Since the distance travelled is the same
Question : If $\sin A=\frac{5}{13}$ and $7 \cot B=24$, then the value of $(\sec A \cos B)(\operatorname{cosec} B \tan A)$ is:
Option 1: $\frac{65}{42}$
Option 2: $\frac{13}{14}$
Option 3: $\frac{15}{13}$
Option 4: $\frac{13}{7}$
Correct Answer: $\frac{65}{42}$
Solution : Given that $\sin A=\frac{5}{13}$ and $7 \cot B=24$, $\sin A=\frac{5}{13}$, Use the identity $\sin^2 A + \cos^2 A = 1$ $⇒\cos A = \sqrt{1 - \sin^2 A} = \sqrt{1 - \left(\frac{5}{13}\right)^2} = \frac{12}{13}$ $\therefore\tan A = \frac{\sin A}{\cos A} = \frac{5}{12}$ $\therefore\sec A = \frac{1}{\cos
Question : Which vitamins are those, if taken in excess can be dangerous as they are stored in the body?
