Question

Answer 1

cost price of one ball=9/10 RS
selling price of one ball=10/9 RS
profit=sp- cp

Answer 2

Given:

Total number of balls = 9

Cost of 9 balls = Rs. 10

Total number of balls = 10

Selling price of 10 balls = 9

To Find:

The gain or loss percentage

Solution:

9 balls = Rs.10/-

10 balls = Rs.9/-

The cost price articles and the selling price articles are always the same.

Therefore,

10(9  10) = 90  100 = Cost price

9(10  9) = 90   81 = Selling price

Therefore,

19/100 × 100

= 19

Answer: There is a loss of 19%.
