This year, the ratio of Jack's age to Keith's age is 3 : 5.

Last year, their average Aachen was 27 years old. How old is Jack now?

Total age last year --> 27 * 2 = 54

 

Total age this year --> 54 + 2 = 56

 

 

             8 --> 56

             1 --> 7

             3 --> 21

 

        Jack's age is 21 yrs old
