Ages

John, Teresa, Daniel and Paul have summary 56 years. Their ages are in a ratio of 1:2:5:6. Determine how many years have each of them.

Correct result:

j =  4
t =  8
d =  20
p =  24

Solution:

x=56/(1+2+5+6)=4 j=1 x=1 4=4x=56/(1+2+5+6)=4 \ \\ j=1 \cdot \ x=1 \cdot \ 4=4
t=2 x=8t=2 \cdot \ x=8
d=5 x=20d=5 \cdot \ x=20
p=6 x=24p=6 \cdot \ x=24
