A man gains 60% by selling an article for a certain price. If he sells it at double the price, the percentage of profit will be. | [
"170%",
"130%",
"320%",
"160%"
] | C | Explanation:
Let the C.P. = x,
Then S.P. = (160/100)x = 8x/5
New S.P. = 2(8x/5) = 16x/5
Profit = 16x/5 - x = 16x/5
Profit% = (Profit/C.P.) * 100
=> (16x/5) * (1/x) * 100 = 320 %
