If the cost price is p then the marked price is 1.4p.
If it is sold after applying a discount of 20%, then the price for sold is 1.4p * 0.8 = 1.12p, or higher than the cost price 12%.

Let the cost price of Laptop be 100

Marked price= 100*$$\frac{140}{100}$$= 140

Discount= 140*$$\frac{20}{100}$$= 28

Selling Price= 140-28= 112

Profit %= $$\frac{112-100}{100}$$*100= 12%

Kudos please if you like my explanation!

Let,
C.P = 100 then,
M.P = 140
discount = 20%
discounted price = 140 - 28 = 112

Profit % = 12% (b)
