The total age of Diana, Carmen, and Andrew is 45. Diana is 21, and Andrew is twice as old as Carmen. How old is Andrew

Answer 1

Diana's age=21 years

Carmen's age=x years

Andrew's age=2x years

21+x+2x=45

21+3x=45

3x=45-21

3x=24

x=24/3

x=8

Carmen is 8 years old and Andrew is 2*8=16 years old
