### Math Riddles With Kids’ Ages

A 35-year-old woman has 3 children. If you multiply the 3 children's ages, you get 36. If you add up the children's ages, it's 13. And her oldest child has played basketball for 3 years. How old are the kids? 👨‍👩‍👧‍👦

They are 2, 2, and 9.

If you list out the trio of factors that multiply to 36, you get:
1 1 36 = 38
1 2 18 = 21
1 3 12 = 16
1 4 9 = 14
6 6 1 = 13
2 2 9 = 13
2 3 6 = 11
3 3 4 = 10

If the sum is 13, as you can see, there are 2 options. When she says her “oldest,” you know it cannot be 6, 6, and 1 since she would have two “older” sons, not an “oldest.”

Can you solve the equation? 💯

Consider the numbers as A + B + C. Now they are following this pattern: A + B + C = [AxB] [AxC] [(AxB)+(AxC)-(B)]

E.g.: 5 + 3 + 2 =
First two digits: 5×3= 15
Further two digits: 5×2= 10
Last two Digits: 15 + 10 = 25 – 3(middle number from question) = 22

14 + 10 - 5 = 19
