Question

If there is a loss of Rs.50 per watch when selling it for Rs.450. Find its selling price to obtain a profit of 20%

Answer 1

if 450 is the loss while selling it for 450 then for no loss and no profit it must be sold for 500. 20% profit is required so the selling price must be 500 + 500*20% =500+100

therefore sell it for 600 to have 20% profit
