Washing powder

A 10-kilogram pack of washing powder is M euros more expensive than a 5-kilogram pack of the same powder. A 5-kilogram package costs P euros. Five kilos of packaging is not worth it, because it is more expensive than half the price of 10 kilos. How much is 1 kg of a 10-kilogram pack cheaper than 1 kg of a 5-kilogram pack? Express the result using the parameters M, P.

Result

p = % (Correct answer is: 50 * (P-M)/P) Wrong answer

Solution:

m5=P m10=M+m5=M+P m5>m10/2 p=100 m5/5m10/10m5/5 p=100 m5m10/2m5 p=100 P(M+P)/2P p=100 2PMP2P p=100 PM2P p=50 PMP p=50 (PM)/P
