Question

A librarian purchased 50 story books for his library. But he
saw that he could get 14 more books by spending Rs. 76
more and the average price per book would be reduced by
Rs. 1. The average price (in Rs.)of each book he bought,
was:​

Answer 1

Answer:

10 rs

Step-by-step explanation:

=> 50x+76(50+14)=(x−1)

=> 50x+7664=x−1

=> 50x + 76 = 64x - 64

140 = 14x

x = Rs.10

Therefore average price of 1 book = Rs. 10
