A shopkeeper mixes two types of wheat, each costing ₹45/kg, so that by selling the resultant mixture at ₹55/kg, he makes a profit of 10%. In which ratio did he mix them?

3:10
1:1
8:5
2:7

Correct answer: 1:1

Solution

A 10% profit on selling at ₹55/kg means the cost price is ₹50/kg. Since both types of wheat cost ₹45/kg, the mixture cost would remain ₹45/kg regardless of ratio, so the intended ratio from the given options is 1:1.
