Question

A shopkeeper buys a number of books for Rs. 80.. If he had bought more books for the same amount, each would have cost him Rs.1 less. How many books did he buy?

Answer 1

read the number of books purchased for Rs 80 = x.
then cost of each book = 80/x
if he buys for more books , then the no.of book = x + 4.
cost of each book = 80/ x + 4
( 80/ x ) - [ 80/ ( x+4 ) ] = 1.
solve then x = -20. (or) x = 16.

then the number of book purchase = 16
