Men Can Complete A Piece Of Work In 18 Days. In How Many Days Will 27 Men Complete The Same Work ?

Answer»

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.
