Question
Neha earns 30% more than Sneha. Neha saves 40% of her
salary, while Sneha saves 10%. If the difference in their spending is Rs. 720, what are Neha’s total savings?Solution
ATQ,
Let Sneha’s income be Rs. 100n
Neha’s income = 1.3 × 100n = Rs. 130n
Expenditure of Neha = 0.6 × 130n = Rs. 78n
Expenditure of Sneha = 0.9 × 100n = Rs. 90n
So, 90n - 78n = 720
Or, 12n = 720
Or, n = 60
Savings of Neha = 130n - 78n = 52n = 52 × 60 = Rs. 3,120
