Question 1

A salesman is on a tour and has Rs. 240 for his expenses. If he exceeds his tour by 4 days, then he has to cut down his daily expenses by Rs. 10. What is the duration of his tour?

10 days.

12 days.

8 days.

14 days.

Soln.
Ans: c

Let the duration be x days. We have $240/x$ - $240/{x + 4}$ = 10. This equation can now be solved, or you can try substituting the options one by one, to obtain x = 8 days.

Question 2

When a certain amount of money was distributed among 8 boys, each of them got Rs. 36 more than the amount received by 14 boys when the same amount was distributed among them. What was the amount?

Rs. 672.

Rs. 674.

Rs. 670.

Rs. 676.

Soln.
Ans: a

If x is the amount, $x/8 - x/14 = 36$, which can be re-arranged to get x = ${36 × 14 × 8}/{14 - 8}$ = Rs. 672.

Question 3

Out of a collection of only blue and pink marbles, 2 pink marbles are removed away. After that there are 2 blue marbles for every pink marble. Next, 36 blue marbles are removed away. As a result, there are 5 pink marbles for every blue marble. How many blue marbles are there at present?

4 marbles.

6 marbles.

10 marbles.

8 marbles.

Soln.
Ans: a

Let the number of blue marbles at present be x. The number of pink marbles at present are 5x. If we put back 36 blue marbles, the equation becomes x + 36 = 2 × 5x, which gives 9x = 36, or x = 4 marbles. Note: some information in the question is never used, it is given for confusing the candidate.

179 marks.

Soln.
Ans: a

Let the score in English be E, then his score in math is 465 - E. We have also been given $(465 - E)/10 = E/25 + 22$. Solving for E, we get E = 175.
