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

• Math -

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 7/3-1 = 4/3, ramesh would be twices as old as rahim.

I think a non-fractional age would have been better. Bogus problem.

• Math -

ramesh's present age --- 5x
rahim's present age ----- 7x

under the "if" situation:

5x+1 = 2(7x-1)
5x+1 = 14x - 2
x = 1/3

Agree with Steve, silly question
