Question
The income of Neha is 60% more than that of Riya. If both
spend 70% of their incomes, then what percent is the expenditure of Riya compared to that of Neha?Solution
ATQ,
Let the income of Riya be Rs. 100x.
So, income of Neha = 1.6 × 100x = Rs. 160x
Expenditure of Riya = 0.7 × 100x = Rs. 70x
Expenditure of Neha = 0.7 × 160x = Rs. 112x
Therefore, required percentage = (70x / 112x) × 100 = (625 / 10)% = 62.5%
