Priya bought 45 kg of apples and mangoes for ₹1,240. The prices of apples and mangoes were ₹25/kg and ₹30/kg, respectively. How much money did she spend on mangoes separately?
Given:
Total weight of apples and mangoes = 45 kg
Total cost = ₹1,240
Cost of apples = ₹25/kg
Cost of mangoes = ₹30/kg
Solution:
Let the weight of apples be x kg. Then,
Weight of mangoes = 45 - x kg
Total cost equation:
25x + 30(45 - x) = 1240
=> 25x + 1350 - 30x = 1240
=> -5x = -110
=> x = 22
So, weight of mangoes = 45 - 22 = 23 kg
Cost of mangoes = 23 × 30 = ₹690
Priya spent ₹690 on mangoes.
