Question

A shopkeeper bought equal quantities of two varieties of wheat, one at a rate of Rs.200 for 4 kg and other variety at a rate of Rs.400 for 10 kg. He mixed the two varieties and sold them at a rate of Rs. 60 per kg. What is the profit/loss percent?
A)33.33% B)40% c)30% d)50%

Answer 1

Total bought wheat = 4 + 10 = 14 kg
Total cp = 400+200 = 600 rs.
Sp of 1 kg = 60 rs.
Total Sp = 60 * 14 = 840 rs.
P = Sp - cp
= 840 - 600 = 240 rs.

P% = p/ cp * 100% = 240/600*100% = 40%


So his total gain is 40 %

Answer 2

Answer:this is wrong ,answer will be 33.33%

Lets think by yourself.

One verity 200 for 4 kg,it means 1 kg for 50 ruppe

Other variety ,400 for 10 kg

It means 1 kg =40 ruppe

It means 2 kg =90 kg(50rs +40rs)

It means 1 kg =45 kg

Quantities are mixed together,and and sold at 60 rs/kg.

Profit is 60-45=15

Profit%= 15/45

1/3=33.33%
