Explanation:

Average price of 15 books = 4500/15 = Rs. 300

Let the average price of 13 books purchased from MN distributors be a.

∴ 300/6 = a/5 

∴ a = 250

∴ Price of books purchased from MN distributirs = 250 × 13 = 3250

∴ Price of books purchased from UV Publishers = 4500 – 3250 = Rs. 1250

Let the two books purchased from UV publishers cost Rs. x and Rs. y.

∴ x/3 = y/2
As x + y = 1250

∴ x = 750 and y = 500

Hence, option (c).
