Question

A salesman is on a tour and has Rs. 150 for his expenses. If he exceeds his tour by 1 days, then he has to cut down his daily expenses by Rs. 5. What is the duration of his tour?

A

5 days.

B

7 days.

C

3 days.

D

9 days.

Soln.
Ans: a

Let the duration be x days. We have $150/x$ - $150/{x + 1}$ = 5. This equation can now be solved, or you can try substituting the options one by one, to obtain x = 5 days.
