Answer:

Gwenny's age is 3 years and Bonny's age is 33years

Explanation:

= let Gwenny's age be x

= Then bonny's will be x+30

=Gwenny's age after 12 years will be x+12

= bonny's age will be after 12 years = x+30+12

= x+42

= according to question bonny will be thrice as old as gwenny:

=>3(x+12)=x+42

=>3x+36=x+42

=>3x-x=42-36

=>2x=6

=>x=6\2

=>x=3 years

Gwenny's age is x=3 years

Bonny,s age =x+30=3+30=33years
