Answer:

21,63 are the ages of the

James and his father

Answer 2

The age of James is 21 years old and that of age of James father is 63 years old

Solution:

Given that James father is three times as old as James

Sum of their ages = 84

Let the age of James father be "x" and age of James be "y"

Sum of "x" and "y" = 84

x + y = 84 ---- eqn 1

James father is three times as old as James which means "x" is three times as "y"

x = 3y ----- eqn 2

Plug in eqn 2 in eqn 1:

3y + y = 84

4y = 84

y = 21

Thus the age of James is 21 years old

Now put "y" value in eqn 2:

x = 3(21) = 63

Therefore the age of James father is 63 years old
