If 4 men working 10 hours a day earn Rs. 1600 per week, then 9 men working 6 hours a day will earn how much per week? | [
"Rs 1620",
"None of these",
"Rs 2160",
"Rs 840"
] | C | Explanation :
(Men 4:9) : (Hrs/Day 10:6) :: 1600 : x
hence 4 * 10 *x = 9 * 6 * 1600
or x = 9*6*1600/ 4*10 = 2160

Five men and nine women can do a piece of work in 10 days. Six men and twelve women can do the same work in 8 days. In how many days can three men and three women do the work? | [
"50 days",
"20 days",
"65 days",
"22 days"
] | B | (5m + 9w)10 = (6m + 12w)8
=> 50m + 90w = 48w + 96 w => 2m = 6w => 1m = 3w 5m + 9w = 5m + 3m = 8m
8 men can do the work in 10 days.
3m +3w = 3m + 1w = 4m
So, 4 men can do the work in (10 * 8)/4 = 20 days.

] | B | Suppose they meet x hours after 10 a.m. Then,
(Distance moved by first in x hrs) + [Distance moved by second in (x-1) hrs]=390.
65x + 35(x-1) = 390 => 100x = 425 => x = 17/4

Two trains are traveling on parallel tracks in the same direction. The faster train travels at 130 miles per hour, while the slower train travels at 100 miles per hour. At 2 o’clock the faster train is 15 miles behind the slower one. How far apart are the two trains at 5 o'clock? | [
"80 miles",
"120 miles",
"75 miles",
"60 miles"
] | C | Answer = C. 75 miles
Relational speed = 130 - 100 = 30 miles per hour
In 3 hours, difference = 30 * 3 = 90 miles
Fast train trailing 15 miles, so effective difference = 90 - 15 = 75 miles | AquaRat_train |

Required number of male employees who are less than 50 years old = 4160 * (100 - 25)%
= 4160 * 75/100 = 3120.

For election of vice-captain, we have only 11 ways left, coz 1 way is already consumed. (Situations like this is called dependent situation. One selection depends upon other selection.)
So, the ans is 12*11 = 132 ways.

A can complete a project in 20 days and B can complete the same project in 30 days. If A and B start working on the project together and B quits 5 days before the project is completed, in how many days total will the project be completed? | [
"10",
"14",
"12",
"18"
] | B | A's rate is 1/20 of the project per day.
B's rate is 1/30 of the project per day.
The combined rate is 1/12 of the project per day.
In the last 5 days, A can do 1/4 of the project.
Thus A and B must complete 3/4 of the project, which takes 9 days.
The total number of days is 9 + 5 = 14.

The captain of a cricket team of 11 members is 29 years old and the wicket keeper is 3 years older. If the ages of these two are excluded, the average age of the remaining players is one year less than the average age of the whole team. What is the average age of the team? | [
"20 years",
"26 years",
"22 years",
"23 years"
] | B | Explanation:
Let the average age of the whole team by x years.
11x – (29 + 32) = 9(x -1)
11x – 9x = 52
2x = 52
x = 26.
So, average age of the team is 26 years.
