Sales stores

The first sales store passed the 1/3 and the second 2/5 of the total amount of goods.In third store passed the 2/3 rest of the goods. The remaining 40 kg of goods put into fourth store. How many kilograms of goods pass to a third store?

Correct result:

x =  80 kg

Solution:

x=(2/3) 3 40=80 kg

1/3y = 40
2/3y = x

1/3•y = 40
2/3•y = x

y = 120
3x-2y = 0

x = 80
y = 120
