When Luna was 4, she was 1/4 of her brothers age. Her brother is now twice his age. How old is Luna and her brother?

Answer 1

when Linda was 4 she was 1/4 her brother's age, so he was 16

Now he's twice Linda's age

16+x = 2(4+x) = 8+2x

x= 8

Brother is now 24 and Linda is now 12

24 is twice 12

8 years ago, she was 4, and he was 16

then she was 1/4 his age.
