Q. How to solve this type of Aptitude questions ? In a dairy farm, 40 cows eat 40 bags of husk in 40 days. In how many days one cow will eat one bag of husk?

Answer :

Hi Tulasi,

Really an interesting question !!


Topic: Aptitude, Logical reasoning and Quantitative Aptitude

Concept : Apply the concept of deducting to one unit. See the method below to solve these kind of questions.

Method : 

  • 40 Cows ==> eat 40 Bags ==> in  40 Days
  • Think that each cow is eating seprately a different bag. (For clarity sake).
  • So 40 Cows eat 40 Bags  means Each 1 Cow eats 1 Bag individually. Time remains same.  Isn't it?
  • Hence 1 Cow ==> will eat 1 Bag  ==> in  40 Days

So idea here is to resolve the situation to one unit.
