Question

A small tank is $\frac{2}{5}$ full of water is then poured into a large empty tank which has a capacity that is twice that of the small tank. What fraction of the large tank is filled with water?

• A. $\frac{3}{5}$
• B. $\frac{2}{5}$
• C. $\frac{1}{5}$
• D. $\frac{4}{5}$

Answer 1

Answer: (C)

$\frac{1}{5}$

Let capacity of the small tank be$x$.
Therefore, Capacity of the large tank will be 2$x$.
Water in small tank = $\frac{2}{5}x$
Required fraction = $\frac{2x}{5}÷2x$= $\frac{1}{5}$
