A taxi charge consists of a fixed fee plus a charge per km. If for 10 km the charge is Rs 150 and for 15 km it is Rs 200, find the fixed fee.
ARs 50
BRs 10
CRs 100
DRs 20
✓ Correct Answer: A — Rs 50
Let fixed fee be F and rate be R. F + 10R = 150, F + 15R = 200. Subtracting gives 5R = 50 -> R = 10. F + 10(10) = 150 -> F = 50.
