Question 1121815
A man sells two articles each for the same price of #640. He earns 20% profit on the first and 40% profit on the second .find the overall percent profit
<pre>If he sells the lower-profit item for $640, and made a 20% profit, then he paid: {{{640/1.2}}} for that item.
If he sells the higher-profit item for $640, and made a 40% profit, then he paid: {{{640/1.4}}} for that item.
We then get total COST as: {{{matrix(1,3, 640/1.2, "+", 640/1.4)}}}
Therefore, his OVERALL profit percent = {{{highlight_green(matrix(1,6, (("1280" - (640/1.2 + 640/1.4))/(640/1.2 + 640/1.4)) * 100, "=", "29.2307692,", rounded, to, "29.23"))}}}
