Explanation:
Let 'x' and 'y' be the average price of 13 books obtained from MN Distributors and remaining 2 books purchased from UV Publishers
respectively.
It is given that he spent a total of Rs. 4500. Therefore,
13x + 2y = 4500 ... (1)
It is also observed that one-sixth of the average price of all the 15 books purchased is equal to one-fifth of the average price of the 13
books obtained from MN Distributors.
... (2)
Form equation (1) and (2) we can say that 2y = 1250.
Let 'a' and 'b' be the price of two books purchased from UV Publishers. It is given that one-third of the price of one volume is equal to
one-half of the price of the other.
Therefore, ... (3)
Also, ... 2y = 1250 = a + b (4)
From, equation (3) and (4) we can say that a = 750 and b = 500. Hence, option C is the correct answer.
