C
Rs.340

D
Rs.300

Solution

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