Question

2 Find the
cost price when :
Selling bice = { 72, Profit
Profit=20%​

Answer 1

Step-by-step explanation:

CP = ?

SP = 72

Profit % = 20 %

profit is on the CP

now,

SP = CP + 20% of CP

72 = CP + 20/100 x CP

72 = CP + 1/5 x CP

72 = CP + CP/5

72 = 6CP/5

72 x 5 = 6CP

360 = 6CP

360/6 = CP

60 = CP

so cost price is 60
