Question

1) Three tanks have a total capacity of 528 gallons. Ir two tanks are the same size and other tank is half of their size, now many gallons does the smallest tank hold?

Answer 1

Let

2x be size of the two tanks of the same size

x the size of the smaller tank

The sum of their capacity is 528 gallons which can be expressed as

`\begin{gathered} 2x+2x+x=528 \\ 5x=528 \\ (5x)/(5)=(528)/(5) \\ x=105.6 \end{gathered}`

Therefore, the size of the smallest tank is 105.6 gallons.
