You would have to use guess and check. Well, that's the method I did. Find a number higher than 50 that's a multiple of three then divide it. That would be your answer.

When Shuyi is 10, her dad is 50.
So, find a multiple of 3 that is bigger than 50 and put it as the dad's age.
For Shuyi, just get another multiple of 3, but make sure that it's lesser 50 but more than 10.
