# Collecting day

On collecting day at school, pupils of three classes took a 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 in each class?

a =  252
b =  378
c =  433

### Step-by-step explanation:

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
