A man bought 13 articles at 70 Rs. each, 15 at 60 Rs. each and 12 at 65 Rs. Each. Then find the average price per article :
[A]60.25 Rs.
[B]62.25 Rs.
[C]64.75 Rs.
[D]65.75 Rs.

64.75 Rs.
Required Average price =
$= \frac{13\times 70+15\times 60+12\times 65}{13+15+12}$
$= \frac{910+900+780}{40} = \frac{2590}{40} = 64.75\ Rs.$
Hence option [C] is correct answer.
