Savita spends 20% of her monthly income on groceries, 15% of the remaining on rent and then 60% of the left over on children's education and others. If she saves ₹9,792 a month, then how much (in ₹) does she spend on rent?
Answer & explanation
Correct answer: option 4
Let total salary of Savita = 100x
Expenditure on Groceries = 20% of 100x = 20x
Remaining amount = 100x - 20x = 80x
Expenditure on Rent = 15% of 80x = 12x
Remaining amount = 80x - 12x = 68x
Expenditure on children education and others = 60% of 68x = 40.8x
Savings = 100x - 20x - 12x - 40.8x = 27.2x
According to question ,
27.2x = 9792
x = 360
Money spend on Rent = 12 x = 12 × 360
= 4320
