Question

A salesman is on a tour and has Rs. 450 for his expenses. If he exceeds his tour by 15 days, then he has to cut down his daily expenses by Rs. 15. What is the duration of his tour?

A

15 days.

B

17 days.

C

13 days.

D

19 days.

Soln.
Ans: a

Let the duration be x days. We have $450/x$ - $450/{x + 15}$ = 15. This equation can now be solved, or you can try substituting the options one by one, to obtain x = 15 days.
