Boxes

200 boxes have been straightened in three rows. The first was 13 more than in the second, and in the second was one fifth more than in the third one. How many boxes are in each row?

Result

a =  79
b =  66
c =  55

Solution:


200=a+b+c
a= 13+b
b = c/5+c

a+b+c = 200
a-b = 13
5b-6c = 0

a = 79
b = 66
c = 55
