Let the size of MC be x and the size of the husband be y.
then we got the equation from the first comparison, which is 2y-x = 8
and we obtained two equations from the second comparison, which are x-y = 5 if x > y and y-x = 5 if y < x.
After calculating if x > y we got the size of MC is 18cm and the size of the husband is 13cm.
After calculating if y > x we got the size of MC as -2cm and the size of the husband as 3cm.
Hence the size of MC cannot be negative, so the actual size of MC is 18cm and the size of the husband is 13cm.
