33 men can complete a piece of work in 18 days. In how many days will 27 men complete the same work ?  Select the correct option.
A) 22
B) 77
C) 36
D) 25
E) 13
Explanation:   Less Men, means more Days {Indirect Proportion}   Let the number of days be x   then,   27 : 33 :: 18 : x   [Please pay attention, we have written 27 : 33 rather than 33 : 27, in indirect proportion, if you get it then chain rule is clear to you :)]   {\color{Blue} x=\frac{33\times 18}{27}}   x = 22   So 22 days will be required to get work done by 27 men.   22nswer: 22
