According to the question, M - R = 5 years ⇒ 60 - R = 5 ⇒ R = 60 - 5 ⇒ R = 55 years Now, according to the question, R - V = 4 years ⇒ 55 - V = 4 ⇒ V = 55 - 4 V - B = 6 years ⇒ 51 - B = 6 ⇒ B = 51 - 6 ⇒ B = 45 years Now, the age difference between M and B, M - B = 60 - 45 ⇒ 15 years ∴ The age difference between M and B is 15 years.
