Question

A tank is 3/8 of filled tank.If adding 50 gallons of water will fill the tank to the brim， what is the tanks capacity when it is useful?​

Answer 1

Answer:

80 gallons

Step-by-step explanation:

Let total capacity of tank be x gallons.

According to ques., 3/8 of tank is filled.

Thus, 1 - 3/8 => 5/8 is empty.

Now if 50 gallons is added, it is full.

∴ 50 gallons = 5/8 of x

Therefore, x = 50*(8/5) => 80 gallons
