If 20% of (x-y) = 15% of (x+y), then what percent of x is y? | [
"25%",
"22.2%",
"50.5%",
"14.3%"
] | D | 20% of (x-y) = 15% of (x+y)
20/100 (x-y) = 15/100 (x+y)
5x = 35y
Required percentage = y/x *100 = 5y/35y * 100 = 14.28%

"6"
] | D | Let the required number of revolutions made by larger wheel be x.
Then, More cogs, Less revolutions (Indirect Proportion)
14 : 4 :: 21 : x 14 * x = 4 x 21
x = (4 x 21)/14
x = 6.

After the first hour the distance w is 42 km (45-3). Now the problem can be treated as if bothof them started at the same time. Since the speeds are in the ratio 3 : 4, the distances will also be in the same ratio. Splitting 42 in that ratio we get 18 : 24. So answer is 24.

A, B and C started a business with a total investment of Rs. 72000. A invests Rs. 6000 more than B and B invests Rs. 3000 less than C. If the total profit at the end of a year is Rs. 8640, Find C's share. | [
"None of these",
"Rs. 3360",
"Rs. 2880",

] | C | Explanation:
Let C's investment = Rs. x
B's investment = Rs. (x - 3000)
A's investment = Rs. (x - 3000 + 6000) = Rs. (x + 3000)
Now, (A + B + C)'s investment = Rs. 72000
=> x + (x - 3000) + (x + 3000) = 72000
=> 3x = 72000
=> x = 24000
Hence, A's investment = Rs. 27000
B's investment = Rs. 21000
C's investment = Rs. 24... | AquaRat_train |

The manager of a produce market purchased a quantity of tomatoes for $0.80 per pound. Due to improper handling, 10 percent of the tomatoes, by weight, were ruined and discarded. At what price per pound should the manager sell the remaining tomatoes if she wishes to make a profit on the sale of the tomatoes equal to 10 ... | [
"$0.98",
"$0.94",
"$0.96",
"$1.00"
] | A | Assume the manager bought 100 tomatoes.
Cost Price = 80
Given: 10% are damaged --> Available tomatoes to sell = 90
90 * x - 80 = 0.1 * 80
90x - 80 = 8
90x = 88
x = 88/90 = 44/45 = 0.977
x is slightly under 0.977= 0.98
