A is 3 years younger than C but one year older than D. D is one year older than B but 4 years younger than C. C is 15 years old. What is the age of B in years?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → 10
Each statement links two people by a difference in years, so the ages are found one after another, starting from C, the only age given.
C is 15 years old.
D is 4 years younger than C: \(15-4=11\) years
D is one year older than B, so B is one year younger than D: \(11-1=10\) years
