Question:

The cost price of type A apples is ₹120 per kg and that of type B apples is ₹180 per kg. If both types of apples are mixed in the ratio 2 : 3 respectively, then what is the price per kg of mixed

Options:

152

156

160

164

Correct Answer:

156

Explanation:

The correct answer is option (2) : 156

c= ₹120 per kg.

d= ₹180 per kg.

So, $\frac{\text{quantity of cheaper apples}}{\text{quantity of dearer apples}}=\frac{2}{3}$

 Let the price of mixed apples be m per kg

Then

$\frac{2}{3}=\frac{180-m}{m-120}$

$2m-240= 540-3m$

$5m= 780=156$
