Solution
The correct option is A 9
Let presen age of Sumeet = x
5 years ago SUmeet age = x-5
9 years later Sumeet' s age = x+9
(x−5)(x+9)=15
x2+4x−45=15
(x+10)(x−6)=0
x=6
3 years from present Sumeet's age =x+3
=6+3
= 9 years
Let presen age of Sumeet = x
5 years ago SUmeet age = x-5
9 years later Sumeet' s age = x+9
(x−5)(x+9)=15
x2+4x−45=15
(x+10)(x−6)=0
x=6
3 years from present Sumeet's age =x+3
=6+3
= 9 years
