    Great concept. But it's debatable if this much long question will come in CAT.
    But the thing to note is, CONCEPT. I don't think that this much level of classy concept (Concept inside a concept) will be anywhere else, and also it's very important to note. So ya question could be irrelevant from CAT point of view, but the small concepts used, is very important.

      It can be solved easily also
      Find Area of sector (Angle - 90), r - 34m... Subtract 2 x Area of sector, Angle- 90 and r - 4m.... will get 882.32
      where r - 34 represent total sector cow can gaze subtract the area which falls outside of Square (i.e 34-30)

    I can solve that cow question in another way. Find Area of sector (Angle - 90), r - 34m... Subtract 2 x Area of sector, Angle- 90 and r - 4m.... will get 882.32
    where r - 34 represent total sector cow can gaze subtract the area which falls outside of Square (i.e 34-30)
    BTW got the same answer but different approach

      Can you please explain it more clearly, I did not understand how did you get the answer. Give a detailed explanation.

    • @dddd6527
      @dddd6527 Рік тому +1

      @@dhishaa_a what is done here by sir is - area grazed by cow inside square is calculated
      What we did is subtract the area grazeable by 34 meter rope - area grazeable but outside the square
      So for example in the diagram
      The solution will be
      AB - is the side of square but rope is bigger so let's assume rope is AX
      So AX will be radius of the circle as explained
      Now, area of sector with length AX and angle 90°( it's a square and circle with centre A )
      Subtract the area of two small sectors outside circle,
      Sectors of AX-AB and same sector made on the above side
      Which are 2 sectors with length =20√3- 30 which is approx 4
      So area of big sector - area of 2 small sectors = 882.32 which is approx sir's answer.
      Hope you can visualise

    Sir while calculating the angles, if angle CAB is 30° and BCA is 60° then in opposite other shape it's just opposite of the shape it should be 60° according this but you considered it too 30°
