Question

If the selling price of 18 chairs is equal to the selling price of 16 chairs, find the gain or loss percent? ​

Answer 1

Step-by-step explanation:

Let, CP of 1 chair be x.

CP of 18 chairs is 18x=SP of 16 chairs.

CP of 16 chairs =16x

Since, SP>CP

Profit=SP−CP

=18x−16x=2x

Profit(%)=

CP

profit

2x

×100

=12.5%

Answer 2

Answer:

12.5 %

Step-by-step explanation:

let the cost price of one chair is x rs

so cost of 18 chairs = 18x

selling price of 16 chairs = 18x

so selling price of 1 chair is = 18x /16

= 9x /8

cost price x rs

selling price 9x /8 rs

so profit = 9x /8 - x

= 9x - 8x /8

profit = x /8 rs

x rs cost

x/8 profit

100 rs cost

profit percentage = 12.5 %
