Question

A merchant purchased 28 Kg of wheat at the rate of 3.00 Rs./Kg, and 72 Kg wheat at 2.00 Rs./Kg. At what rate must he sell the mixture to make an overall gain of 5%?

A

2.39.

B

3.39.

C

1.39.

D

4.39.

Soln.
Ans: a

The overall cost is $28 × 3 + 72 × 2$ = Rs. 228. Add a profit of 5% to get SP = $228 + (5 × 228)/100$ = Rs. 239.4. So the rate = $239.4/{28 + 72}$ = $239.4/100$ = 2.39.
