SOURCE: Tom is 5 times as old as todd.In seven years
Let m be Tom's age and d be Todd's age.
Nowm = 5 x d
In seven years
m + 7 = (d + 7) x 3 + 6
By substituting m
5 x d + 7= (d + 7) x 3 + 6
By simplifying
d = 10
Therefore
m = 50
The age of Sam now = 5
The age of Tom now = 5 x 3 = 15 (as he is three times older than Sam now)
When Sam is 20 he might have passed 15 years. That 15 years should be added to Toms age; that is 15+15 = 30.
