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?

Result

x =  80 kg

#### Solution:

$x=(2/3) \cdot \ 3 \cdot \ 40=80 \ \text{kg}$

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

y = 120
3x-2y = 0

x = 80
y = 120
