    Explanation:
    A2001:A2002 = 4:5
    A2001:B2001 = 2:3
    We have to make A2001 same in both cases.
    A2001:B2001 = 4:6
    Let A’s income in 2001 = 4x
    Let B’s income in 2001 = 6x
    A and B income in 2001 = 25000[Given]
    10x = 25000
    x = 2500
    A’s income in 2001 = 4x = 4*2500 = Rs10000
    B’s income in 2001 = 6x = 6*2500 = Rs15000
    A’s income in 2002 = 5x = 5*2500 = Rs12500
    Savings of A in 2002 = Rs4000
    Expenditure = Income – Savings = 12500 –4000 = Rs8500
