A librarian purchased 50 storybooksfor his library,but he saw that he could get 14 more books by spending rs76 more and the average price per book would be reduced by re 1.then the average price of each book he bought was?

• Let x be average price.
  So total value 50x.
  According to question
  64(x-1)=50x+76
  x=10

• x/50=y,,
  x+76/64=y-1
  solving both equations we get y=10 and x=500 so
  avrg price per book is 9

• Let average price per book is x
  i.e. (total books price) / 50 = x
  now given that he can buy 14 more books by spending Rs. 76 more which will reduce the average price by 1, so
  (total books price)/50+14 = (x-1)
  i.e. (50x+76)/64 = (x-1)
  on solving we'll get x=10 ( average price per book)

• total cost =50x
  a/q
  64(x-1)=50x+76
