Question

Mia's age is a 2 digit number which is a multiple of 2 and divisible by 3. Also, she is younger than 17 years old. How old is she?

Answer 1

Mia's age is a multiple of 2.
Multiples of 2 : 2 , 4, 6 , 8 , 10 , 12 , 14 , 16 , 18 , 20, 22.......

Out of which are divisible by 3: 6, 12, 18, 24.....
Given condition: Mia's age is a two-digit numbers, so exclude the one-digit number. Now possible numbers are 12, 18, 24...

And she is younger than 17 years old. So exclude the numbers 18, 24.. which are greater than 17.

Hence, Mia's age is 12.
