Question 1091686: A fractionation has a reservoir of water with a storage capacity of 5000m, only that at this moment has 2/5 of its capacity. Two recharges are scheduled: one of 1/4 of the capacity of the tank and another of 1/8. How much water will be left in the tank if it is known that during the week 1/5 of the tank capacity will be used?

%282%2F5%29%2A5000=2000 units of volume in the tank initially.

Recharges: %281%2F4%295000%2B%281%2F8%295000=1875 units to be added.
After the recharges done, 3875 units in the tank.

During the week, use 1%2F5 of capacity.
3875-%281%2F5%295000
3875-1000
2875 units of water will remain.
