Question & answer

Is this your homework? These are really not that tricky. Wouldn't you get more satisfaction working them out yourself?

Hello,
An answer to Q1
If the boy is 4 years old, then his syster taht is 3 times as old as heis, is
3*4=12 years old.
When the boy is 12 years old, namely 12-4=8 years after, then is sister
will be 12+8=20 years old

I hope that the answer is clear

Thank you
