"18",
"15",
"12",
"30"

(10x + 20y)/(x+y) = 15
10x + 20y = 15x + 15y
5y = 5x
y = x
Doesn't work because the problem states that x<y.
We need y to be larger, so let's try answer choice D: s=18
10x + 20y = 18x + 18y
2y = 8x
y/x = 8/2
Success! x<y.

Out of 15 students in a class, 9 are wearing blue shirts, 3 are wearing green shirts, and 3 are wearing red shirts. Four students are to be selected at random. What is the probability that at least one is wearing a green shirt? | [
"58/91",
"68/101",
"48/81",
"28/61"
] | A | Total possible ways to choose 4 students out of 15 = 15C4 = 1365
The number of ways to choose 4 students with no green shirts = 12C4 = 495
P(no green shirts) = 495/1365 = 33/91
P(at least 1 green shirt) = 1 - 33/91 = 58/91

A is twice as good a work man as B and together they finish a piece of work in 14 days.The number of days taken by A alone to finish the work is : | [
"11",
"42",
"28",
"21"
] | D | Solution
(A’s 1 day’s work): (B’s 1 day’s work)= 2 : 1.
(A + B)'s 1 day’s work = 1/14
Divide 1/14 in the ratio 2 : 1.
∴ A’s 1 day’s work = (1/14 x2/3)= 1/21
Hence,A alone can finish the work in 21 days.

Self made | [
"25",

n*(n - 3)/2 = 230
n*(n - 3) = 460
Substitute n from the answer choices. n = 23

If line L passes through point (m, n) and (– m, – n), where m and n are not 0, which of the following must be true?
I. The slope of L is need not be positive
II. The slope of L is negative
III. L exactly passes through 2 quadrants | [
"II only",
"I and III only",
"III only",
"I only"
] | B | Let (m,n) = (2,3)
(-m,-n) = (-2,-3)
Slope = (3+3)/(2+2) = 6/4 = 3/2
So II may not be true
Let (m,n) = (2,-3) then (-m,-n) = (-2,3)
So slope = (3 +3)/(-2-2) = -3/2
so I may be true
So such a line would be -> (y - 3) = 3/2(x - 2)
=> 2y - 6 = 3x - 6
=> 2y - 3x = 0, hence no x or y intercept, so it passes through origin.

Dawson sold an item for Rs.3600/- and incurred a loss of 10%. At what price should he have sold the item to have gained a profit of 10%? | [
"4100",
"4400",
"4300",

] | B | Explanation:
10% loss means SP = 90% of CP
:. CP = Rs.3600x100/90 = Rs.4000.
The SP for a gain of 10% = 4000+10% of 4000 = 4000+400 =Rs4400.

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. 90000
