Question 1040298
A watch is sold at a profit of 20% on the cost price after allowing a discount of 20% on the marked price. Find the M.P of the watch is a profit of Rs. 100 is made on it.
<pre>Since profit = 20% = $100, cost = {{{matrix(1,3, 100/.2, or, "$500")}}}
Since cost = $500, selling price = 1.2(500), or $600
Since selling price ($600) was discounted at 20%, or was 80% of the marked price, then marked price = {{{highlight_green(matrix(1,3, "$600"/.8, or, "$750"))}}}
