Water container

Container with water weighs 1.48 kg. When we cast 75% of water container of water weight 0.73 kg. How heavy is an empty container?

Result

x =  0.48 kg

Solution:


x+y=1.48
x+(1-75/100)*y=0.73

x+y = 1.48
100x+25y = 73

x = 12/25 = 0.48
y = 1

Calculated by our linear equations calculator.
