Correct answer: A
Let the income in 2003 be x.
Income in 2004 = 1.2x (20% increase over x).
Income in 2005 = 1.2 × 1.2x = 1.44x.
Total income over the three years = x + 1.2x + 1.44x = 3.64x.
Set the total equal to 36,400 and solve for x:
3.64x = 36,400
x = 36,400 ÷ 3.64 = 10,000
Therefore, income in 2005 = 1.44x = 1.44 × 10,000 = 14,400.
Check: 10,000 + 12,000 + 14,400 = 36,400, which matches the given total.
