ram is twice as old as rahim was when ram was as old as
rahim is now.and the combined age of ram and rahim is 210
years.what is ram 's age now?
Answer Posted / 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
