4 men and 6 women finish a job in 8 days, while 3 men and 7 women finish it in 10 days. In how many days will 10 women working together finish it ? | [
"70 days",
"50 days",
"40 days",
"60 days"
] | C | Explanation:
Let 1 man's 1 day work = x
and 1 woman's 1 days work = y.
Then, 4x + 6y = 1/8
and 3x+7y = 1/10
solving, we get y = 1/400 [means work done by a woman in 1 day]
10 women 1 day work = 10/400 = 1/40
10 women will finish the work in 40 days

Rose is two years older than Bruce who is twice as old as Chris. If the total of the age of Rose, B and Chris be 27 years, then how old is Bruce ? | [
"7 years",
"14 years",

"12 years"
] | C | Let Chris's age be x years. Then, Bruce's age = 2x years.Rose's age = (2x + 2) years.
(2x + 2) + 2x + x = 27
5x = 25
x = 5.
Hence, Bruce's age = 2x = 10 years.

In the quadratic equation ax2 - 11x + 40 = 0, if the sum of two roots is 1.1, what is the product of the two roots? | [
"4.2",
"9",
"None of these",
"4"
] | D | Explanation:
The sum of the roots of the quadratic equation ax2 - bx + c = 0 are (-b/a) and the product of the roots are (c/a).
Thus, in the equation ax2 - 11x + 40 = 0, where a = a, b = - 11 and c = 40.
we get, sum of the roots = - (- 11) / a = 1.1
a = 11 / 1.1 = 10
Product of the roots = 40 / 10 = 4

A man gains 50% by selling an article for a certain price. If he sells it at double the price, the percentage of profit will be. | [
"160%",
"130%",

Let the C.P. = x,
Then S.P. = (150/100)x = 3x/2
New S.P. = 2(3x/2) = 3x/1
Profit = 3x/1 - x = 3x/1
Profit% = (Profit/C.P.) * 100
=> (3x/1) * (1/x) * 100 = 300 %
