Question

$10$ sheep and $5$ pigs were bought for $Rs.6,000$. If the average price of a sheep is $Rs.450$, find the average price of pig.

• A. $Rs.380$
• B. $Rs.410$
• C. $Rs.340$
• D. $Rs.300$

Answer 1

The correct option is D $Rs.300$

According to the question,
$\frac{\text{Average price of Pig}\times \text{no. of pig}+\text{Average price of Ship}\times \text{No. of Ship}}{\text{No. of Pig}+\text{No. of Ship}}$
$=$ Total average price
Let average price of $5$ Pigs $=x$
$\frac{5x+10\times 450}{15}=\frac{6000}{15}$
$5x+4500=6000$
$5x=1500$
$x=300$.
