Camel and water

84% of the camel's weight is water. After drinking, its weight increased to 832 kg and water accounted for 85% of its weight. How much did it weigh before drinking?

Correct result:

m =  780 kg

Solution:


0.84 m = w
0.85 (m+x) = w+x
m+x = 832


0.84•m = w
0.85•(m+x) = w+x
m+x = 832

0.84m-w = 0
0.85m-w-0.15x = 0
m+x = 832

m = 780
w = 3276/5 = 655.2
x = 52
