"120 ml",
"100 ml",

Let V be the volume of alcohol added to make the strength 32%
then V/340+V = 32/100. solving this we get V as 160ml
so we need to add 160 -60 = 100 ml of alcohol

A man gains 20% by selling an article for a certain price. If the sells it at double the price, the percentage of profit will be? | [
"91%.",
"66%.",

"140%."
] | D | Let C.P. = Rs. x.
Then, S.P. = Rs. (12% of x) = Rs. 6x/5
New S.P. = 2 * 6x/5 = Rs. 12x/5
Profit = 12x/5 - x = Rs. 7x/5
Profit = 7x/5 * 1/x * 100 = 140%.
