It was calculated that 100 men could complete a piece of work in 20 days. When work was scheduled to commence, it was found necessary to send 50 men to another project. How much longer will it take to complete the work? | [
"40 days.",
"38 days.",
"30 days.",
"35 days."
] | A | One day work = 1 / 20
One man’s one day work = 1 / ( 20 * 100)
Now:
No. Of workers = 50
One day work = 50 * 1 / ( 20 * 100)
The total no. of days required to complete the work = (100 * 20) / 50 = 40

A furniture dealer purchased a desk for $120 and then set the selling price equal to the purchase price plus a markup that was 40% of the selling price. If the dealer sold the desk at the selling price, what was the amount of the dealer's gross profit from the purchase and the sale of the desk? | [
"66.67",
"65",
"80",
"75"
] | A | Anyway, in this question, there is no discount but the mark up is given as 40% of the selling price. So it is not 40% of $150 but instead, 40% of Selling price which is obtained by adding mark up to $120.
So if selling price is S,
120 + 40% of S = S
S = 200
Profit = 80 which is calculated on cost price in % terms. So 8... | AquaRat_train |

"100 m x 200 m",
"100 m x 100 m",

In 4 minutes he covered 4 x 400 = 1600 m
This is equal to the perimeter 2 ( l + b) = 1600
But l : b = 3:2
Let l = 3k, b = 2k
Substituting, we get 2 ( 3k + 2k ) = 1600 => k = 180
So dimensions are 480 x 320
