Question

5. IfS.P of 20 chairs is same as C.P of 21 chairs, find the profit or loss percent?
​

Answer 1

Step-by-step explanation:

Let the CP be 'x'

SP of 20 chairs = 21x

SP of 1 chair = 21x/20

Profit = SP - CP

= 21x/20 - x

= (21x - 20x)/20

= x/20

Profit % = (Profit/Cp)×100

= x/20×1/x×100

= 5%
