Answer 1

Answer:

9 years

Step-by-step explanation:

Hii mate,

let your age be x

and your sister's age be y

According to question,

3y=x    .....(1)

Also, given, after 9 years,

$1\frac{1}{2} (y+9)=x+9$

$=>\frac{3}{2} (y+9)=3y+9$  (from (1))

$=>3(y+9)=2(3y+9)$

=>3y+27=6y+18

=>3y=9

=>y=9/3

=>y=3

so, x=3y=3(3)=9

Hence, your present age is 9 years.
