C Correct answer
Explanation

Let present ages be 2x and 3x. After 18 years: (2x+18)/(3x+18) = 4/5. Cross-multiply: 5(2x+18) = 4(3x+18), giving 10x+90 = 12x+72, so 2x = 18 and x = 9. Q's present age = 3x = 27 years. Option A (25) and B (24) don't satisfy the ratio. Option D (30) would make the future ratio 48:48 = 1:1, not 4:5.
