Schools

Three schools are attended by 678 pupils. To the first attend 21 students more and to the third 108 fewer students than to second school. How many students attend the schools?

Result

a =  276
b =  255
c =  147

Solution:


a+b+c=678
a=21+b
c=b-108

a+b+c = 678
a-b = 21
b-c = 108

a = 276
b = 255
c = 147
