Hamid has three boxes of fruit. Box a weighs 5/2kg more than box B and boxB weighs 41/4kg more than box C. The total weight of the boxes is195/4kg.Howmany kg does box a weighs.?

Answer 1

I will assume that 41/4 is to mean 4 1/4 or 17/4
weight of box C ---- x
weight of box B -----(17/4)x
weight of box A ---- (5/2)(17/4)x or (75/8)x

total weight : 19 5/4 kg or 195/4 kg ??? , the way you typed it. I was going to make the same assumption as above, but why would it be
19 5/4 , that would be 20 1/4

x + 17x/4 + 75x/8 = 195/4
multiply each term by 8
8x + 34x + 75x = 390
110x =390
x = 39/11

sub back into my definitions.
( I still think there is a typo, make the necessary changes)
btw, look at this post from a few years ago
