Answer / dayanand
ANS - 126
suppose present ram age is X and rahim age is Y.
so X+Y = 210
difference b/w ram and rahim age is Z
then X-Z=Y
as per the condition Z years ago
(X-Z) = 2* (Y-Z)
putting Y value
Z = x/3
so 2X-X/3=210
so x=126 years.
if the difference b/w two no is x and after deducting x
from both nos, frist no is twice larger then the second one
so at present frist no would be 3/5 of the sum of the no.
so value of the no is 3*210/5 = 126.

Answer / paul
My answer is 126 years old (age of Ram).
equation:
let x = present age of Ram
y = present age of Rahim
when Ram has the present age of Rahim (y yrs. old), age of rahim is y/2 yrs. old. Since the differences of there age are the same for the 2 events, therefore...
x - y = y - y/2
x = 1.5y
but we are given, x + y = 210
Substituting the equation of x to that equation will give us...
1.5y + y = 210
y = 84
thus, x = 210 - 84
= 126 yrs. old -> age of Ram

Answer / badri
Ram is twice as old as Rahim was (Long ago)
Ram is 2X and Rahim is X
Ram was as old as Rahim is now.
Ram is 3X and Rahim is 2X
combined age of Ram and Rahim is 210 years
3X +2X = 210
5X = 210
X =42
Ram 's age = 3X = 3(42) = 126 years.
