Question

The cost price of 280 items is same as the sale price of N items. If the profit is 40%, then what is N?

A

200.

B

201.

C

199.

D

202.

Soln.
Ans: a

Let the cost per unit be r. CP of N items is rN, and SP of N items is already given to us as 280r. Profit percent is ${{280r - rN}/{rN}} × 100$ = 40. Cancelling r, and solving for N we get N = 200.
