Question

A village lost 12% of his goats in a flood and 5% of the remaining died from diseases. If the number left now is 8360, what was the original number before the flood ?

• A. 9000
• B. 10,000
• C. 11,000
• D. 12,000

Answer 1

Answer: (B)

10,000

Consider the number of goats before flood be $x$

According to the question

$\begin{array}{c}x\times \frac{88}{100}\times \frac{95}{100}=8360\\ \Rightarrow x=\frac{8360\times 100\times 100}{88\times 95}=10,000\end{array}$

Hence, Option $B$ is the correct answer.
