let the age of parul be x
.°. aage of ali=x-2
.°. age of ankur=x+4
thus, A/Q,
x+x-2+x+4=47
3x=47-2
x=45/3
x=15
parul's age = 15 yrs
ankur's age = 15+4=19 yrs
ali's age = 15-2= 13 yrs
.°. aage of ali=x-2
.°. age of ankur=x+4
thus, A/Q,
x+x-2+x+4=47
3x=47-2
x=45/3
x=15
parul's age = 15 yrs
ankur's age = 15+4=19 yrs
ali's age = 15-2= 13 yrs
mayurniki:
first you have to take parul be x
No,you can take anyone's age as x ,
but you have to take first paril then your method been correct
Its not so, x is relative and imaginary. In this tyoe of questions one can let anyones age as x . If one is older than x ,then add that much age from x ,if one is younger than x substract that much from x. Hope you will understand.

Lets age of Ali = x
Age of parul = (x+2)
Age of ankur = (x+2+4) = (x+6)
According to the question
Some of ages =47
x + (x+2) + (x+6) =47
3x+ 8 =47
3x =39
x = 13
Age of Ali = x = 13 years
Age of parul =x+2 = 15 years
Age of ankur = x+6 = 19 years
Hope it helps
