Seven different objects must be divided among three persons. In how many ways this can be done if at least one of them gets exactly one object. | [
"776",
"223",
"196",
"287"
] | C | Division of m+n+p objects into three groups is given by (m+n+p)!m!×n!×p!(m+n+p)!m!×n!×p!
But 7 = 1 + 3 + 3 or 1 + 2 + 4 or 1 + 1 + 5
So The number of ways are (7)!1!×3!×3!×12!(7)!1!×3!×3!×12! + (7)!1!×2!×4!(7)!1!×2!×4! + (7)!1!×1!×5!×12!(7)!1!×1!×5!×12! = 70 + 105 + 21 = 196

The perimeter of a rectangular yard is completely surrounded by a fence that measures 10 meters. What is the length of the yard if the area of the yard is 6 meters squared? | [
"8",
"7",
"5",
"3"
] | D | Perimeter of rectangular yard = 2(l + b) = 10 --> l + b = 5
Area = l * b = 6
b = 5 - l
l(5 - l) = 6
5l - l^2 = 6
l^2 - 5l + 6 = 0
Upon simplifying we get l = 2 or 3. Only 3 is there in the answer choice.

A number x is multiplied with itself and then added to the product of 4 and x. If the result of these two operations is 12, what is the value of x? | [
"-2",
"-4",
"2 and 6",
"4"
] | C | A number x is multiplied with itself --> X^2
added to the product of 4 and x --> X^2+4X
If the result of these two operations is -4 --> X^2+4X=4
i.e X^2+4X-12=0 is the Quadratic equation which needs to be solved.
(X-2)(X+6) = 0
Hence X=2, X=-6

X, Y and Z, each working alone can complete a job in 6, 8 and 12 days respectively. If all three of them work together to complete a job and earn $2350, what will be Z's share of the earnings? | [
"$522.3",
"$550.50",
"$1080.02",
"$525"
] | A | The dollars earned will be in the same ratio as amount of work done
1 day work of Z is 1/12 (or 2/24)
1 day work of the combined workforce is (1/6 + 1/8 + 1/12) = 9/24
Z's contribution is 2/9 of the combined effort
Translating effort to $ = 2/9 * 2350 = $522.3
