A scooter dealer allows a discount of 16% on the marked price .However , he still makes a profit of 20% on the C.P . Find the profit percent he would have

made, had he sold the scooter at the M.P. Please help me doing this sum frndz

Let the marked price be 'M'and cost price be 'C'.
Selling price when 16% is discounted is ' (0.84)M '.
He makes a profit of 20% i.e. (0.84)M-C=(0.20)C → M=(120÷84)C.
If he had sold it at M, the profit fraction he would have made is (M-C)÷C = (120-84)÷(84) = 3/7.
Then profit percent is (3/7)×100%= 42.857%
