Chameli has Rs 600 left after spending 75 per cent of her money. How much did she start with?
ARs 2,000
BRs 1,800
CRs 2,400
DRs 3,000
Answer & Solution
Correct answer: C. Rs 2,400
1. Spending 75 per cent leaves 25 per cent of the original amount.
2. So 25 per cent of the starting money = Rs 600.
3. Starting money = 600 x (100/25) = Rs 2,400.
4. Check: 75 per cent of 2400 = 1800 spent, leaving Rs 600.
