1 answer
weight of karen = k
weight of john = j
by the question
j=3k
then
case II
2j +k =875
2×3k+k=875
7k = 875
k=875/7
k=125
now
j=3k
=3×125
=375
hence john was 375 pound and karen was 125.
2 answer
let Mary be m and joes be j
by question
M=3J
CASE II
M + J=24
3J +J =24
J =24/4
J=6
NOW
M=3×6
M=18
Therefore Mary was 18 yrs old and Joes was 6 yrs old.
