Repairing

Three employees earned a total of € 469 for repairing the equipment. They split so that the first got 20% more than the second, and the third 15% more than the second. How many euros did everyone get?

Correct result:

a =  168
b =  140
c =  161

Solution:


a+b+c=469
a = b + 0.20 b
c = b + 0.15 b

a+b+c=469
a = b + 0.20•b
c = b + 0.15•b

a+b+c = 469
a-1.2b = 0
1.15b-c = 0

a = 168
b = 140
c = 161
