• B. 30 years
• C. 15 years
• D. 20 years

Answer 1

Answer:

D. 20 years

Given A is 25 years younger than B. A = B - 25 ............. (i) Age of B would be double the age of C after 15 years. (B + 15) = 2(C + 15) B + 15 = 2C + 30 ............ (ii) The current age of B is three times the current age of C. B = 3C ........... (iii) 3C + 15 = 2C + 30 C = 15 years B = 3 × 15 B = 45 years A = B - 25 A = 45 - 25 A = 20 years age of A is 20 years.
