boysagenow = 11

girlagenow = boy age now + difference

                       = 11+6= 17

Answer 2

The age of sister will be 17

Given:

Age of boy = 3 years

Age of sister = Three times of the boy

To find:

Age of sister when the boy will be 11 years old

Solution:

Since the age of the boy is 3 and the sister is three times his age.

Therefore,

Sister's age

= 3 × 3

= 9

Calculating the difference in their ages

= 9-3

= 6

As it is given that the boy's age now is 11

Thus,

Calculating the age of the sister -

Sister's age now = Boy's age now + Difference in their age

= 11 + 6 = 17

Answer: The age of sister will be 17
