  • Question
  • 36 men can complete a piece of work in 18 days. In how many days will 27 men complete the same work ?


  • Options
  • A. 24 days
  • B. 28 days
  • C. 34 days
  • D. 35 days

  • Correct Answer
  • 24 days 

    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.
