Let durva's present age be x
Poorva present age be x+6
After 3 yrs,
Durva's age= x+3
Poorva's age= x+9
Now,
x+9/x+3=4/3
3(x+9)=4(x+3)
3x+27=4x+12
4x-3x=27-12
x=15
Therefore,
Durva's age= 15 yrs
Poorva's age= x+6= 15+6= 21 yrs
Poorva present age be x+6
After 3 yrs,
Durva's age= x+3
Poorva's age= x+9
Now,
x+9/x+3=4/3
3(x+9)=4(x+3)
3x+27=4x+12
4x-3x=27-12
x=15
Therefore,
Durva's age= 15 yrs
Poorva's age= x+6= 15+6= 21 yrs
