The age of ramesh and rahim are in the ratio 5:7. If ramesh was a years oldr and rahim was a years younger,the age of ramesh would have been twice age of rahim.find their age
plz gve me sltn fst

if ramesh=x, rahim = 7/5 x
x+1 = 2(7/5 x  1)
5x+5 = 14x  10
9x = 15
x=5/3
so, ramesh is 5/3, rahim is 7/3
if ramesh were 5/3+1 = 8/3, and rahim were 7/31 = 4/3, ramesh would be twices as old as rahim.
I think a nonfractional age would have been better. Bogus problem. 
ramesh's present age  5x
rahim's present age  7x
under the "if" situation:
5x+1 = 2(7x1)
5x+1 = 14x  2
x = 1/3
Agree with Steve, silly question
