View Answer
Correct choice: A
Explanation:
Less Men, means more Days {Indirect Proportion} Let the number of days be x then, 27 : 36 :: 18 : x [Please pay attention, we have written 27 : 36 rather than 36 : 27, in indirect proportion, if you get it then chain rule is clear to you :)] =>27x = 36 * 18 => x = 24 So 24 days will be required to get work done by 27 men.
