Given - Selling price and profit percentage

Find - Cost price

Solution - Cost price = 100/(100 + profit percentage)*selling price

Keep the values in formula to find the cost price.

Cost price = 100/(100 + 20)*540

Cost price = 100*540/120

Performing multiplication in numerator

Cost price = 54000/120

Performing division

Cost price = 450
