Rahim is now 10 years youngere than karim. If in 5 years karim becomes twice as old as rahim, how old will rahim be in 3 years ?
সমাধান
সঠিক উত্তর: Option A
Let, Karim is x years old
So, Rahim = (x-10) years old
According to question,
(x+5) = 2(x-10+5)
=> x+5 = 2x-10
=> x=15
So, After 3 years Rahim will be = x-10+3 = 8 years (Ans.)
