Question

A cask containing $425$ litres lost $8\%$ by leakage and evaporation. The number of litres left in the case were:

• A. $\frac{425\times 8}{100}$
• B. $425+\frac{425\times 8}{100}$
• C. $425-\frac{425\times 8}{100}$
• D. $425\times \frac{425\times 8}{100}$

Answer 1

Answer: (C)

$\Rightarrow$ Total liters in cask = $425liters.$

$\Rightarrow$ Lost by leakage $=8\%$

$\Rightarrow$ The amount wasted $=8\%$ of $425=425\times \frac{8}{100}$

$\Rightarrow$ The number of liters left in case $=$ Total liters $-$ The amount wasted

$\Rightarrow$ The number of liters left in case $=425-\frac{425\times 8}{100}$
