Collecting day

At collecting day at school pupils of three classes took total of 1063 kg of paper. Class B collected half more than A Class and class C 55 kg more than B. How many kg of paper collected each class?

Correct result:

a =  252
b =  378
c =  433

Solution:


a+b+c=1063
b = a+a/2
c = b + 55

a+b+c = 1063
3a-2b = 0
b-c = -55

a = 252
b = 378
c = 433
