36 men can complete a piece of work in 18 days. In how many days will 27 men complete the same work ?  Choices
A) 24 days	B) 28 days	C) 34 days	D) 35 days	E) None of these
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 :)]   x=36∗18 / 27   x=24   So 24 days will be required to get work done by 27 men.   Option 24 days
