Question

Mufasa is 3 years older than Rafiki and Simba is twice as old as Mufasa. The sum of their ages is 57. How old is Mufasa?

Answer 1

Mufasa's age is `15` years.

Explanation:

Let Rafiki's age is `R`

Then Mufasa's age is `M=R+3`

And Simba's age is `S=2M=2*(R+3)=2R+6`

The sum of their ages is `R+M+S =57 or R+R+3+2R+6=57 or 4R =57-9 or 4R=48 or R=12 ; M=R+3=12+3=15`

Mufasa's age is `M=R+3=15` years [Ans]
