Answer: 33
Step-by-step explanation:
12+3=15, so in 3 years time Ruto will be 15.
Because 15 is said to be 1/3 times his fathers present age (x), you can plug that into an equation.
15=1/3(x)
Then solve the equation.
(3)15=[1/3(x)]•3
45=x
His father is currently 45, so if you subtract 12 from that, you get 33.
Ruto’s father was 33 years old 12 years ago.
