Answer by palanisamy(496) (Show Source):
You can put this solution on YOUR website! Let the age of Gamma = x
Let the age of Tony = y
Given, Five Years ago, Gemma was twice as oldas Tony is now
x-5 = 2y ...(1)
Also. In seven years, Gemma will be five times as old as Tony is now.
x+7 = 5y ...(2)
(1)-(2)=>
-5-7 = 2y-5y
-12 = -3y
3y = 12
y = 12/3
y = 4
(1)=> x-5 = 2*4
x = 8+5 = 13
So, at present the age of Gamma = 13
and the age of Tony = 4
