The ratio of income of A and B is 5:4 and their expenditure ratio is 3:2. If at the end of the year, each saves Rs 1600, then the income of A is:
ARs 4000
BRs 3200
CRs 4800
DRs 2000
✓ Correct Answer: A — Rs 4000
(5x-1600)/(4x-1600) = 3/2 => 10x-3200 = 12x-4800 => 2x=1600 => x=800. A's income = 5*800 = 4000.
