1. Some persons can do piece of work in 12 days. Twice the number of such persons will do half of that work in, how many days.
SHOW ANSWER
Correct Ans:3

We will use our logic.
Some number of people complete the work in 12 days.
Number of people and time taken to complete the work is inversely proportional
Twice the people, will reduce the time by half.

2. In a dairy farm, 40 cows eat 40 bags of husk in 40 days. In how many days one cow will eat one bag of husk.
SHOW ANSWER
Correct Ans:40
Explanation:
Less number of cows, more number of days (indirect proportion)
Less bags, less days (direct proportion)
Cows, 1 : 40 :: 40 : x
Bags , 40 : 1 :: 40 : x
---> (x) x 40 x 1 = 40 x 1 x 40
---> x= 40
4. 39 persons can repair a road in 12 days, working 5 hours a day. In how many days will 30 persons, working 6 hours a day, complete the work?
SHOW ANSWER
Correct Ans:13
Explanation:
Let the required number of days by x
Less person, more time (Inverse proportion)
Persons => 30 : 39 :: 12 : x
Time => 6 : 5 :: 12 : x
Therefore 30 x 6 x (x) = 39 x 5 x 12 => x = (39 x 5 x 12) / ( 30 x 6)
x = 13
6. An industrial loom weaves 0.128 meters of cloth every second. Approximately, how many seconds will it take for the loom to weave 25 meters of cloth?
SHOW ANSWER
Correct Ans:195
Explanation:
Given, In 1 second, cloth weaved = 0.128 meters
To weave 1 meter cloth, time taken = (1 / 0.128) seconds
To weave 25 meters of cloth, time taken = (1 / 0.128) X 25 seconds
= 195 seconds (approximately)
9. 36 men can complete a work in 18 days. In how many days will 54 men can complete the same work?
SHOW ANSWER
Correct Ans:12
Explanation:
Less men means more days ( Inverse proportion)
54 : 36 :: 18 : x => x = (36 x 18) / 54 = 36 / 3 = 12
Required number of days = 12, with 54 people working on it.
