Question

Jane's age is a 2 digit number which is multiple of 8. She is younger than 20 years old. How old is she?

Answer 1

Jane's age is a multiple of 8.
: 8, 16, 24, 32,40

And she is younger than 20 years old. So exclude the one digit number and also numbers greater than 20. So, Jane's age is 16.
