Step-by-step explanation:

If cost price (CP) is greater than selling price (SP) , then the item is sold for loss.

Loss = CP - SP

Loss% = $\frac{loss}{CP}*100$

If SP is greater than Cp, then the item is sold for a profit.

Profit =SP -CP

Gain % = $\frac{gain}{CP}*100$

a) CP = $50 ; SP = $30 ; CP > SP, loss

Loss = 50 - 30 = $ 20

Loss % = $\frac{20}{50}*100=20*2$

= 40% loss

b) CP = £ 5000 ; SP = £6250 ; SP > CP , Profit

Profit = 6250 - 5000 = £ 1250

Profit % = $\frac{1250}{5000}*100=25$

25% Profit
