Comparison Based Problems are very common questions in competitive exams and easy to solve if approach a best strategy. In solving such type of questions stop guessing and start a strategy plan by working out in a paper.
To solve Comparison based problems read and understand the given problem clearly, now solve it in a diagrammatical way.
Read the following information and answer the questions given below it:
Example 1: There are five friends Sandeep, Kiran, Madhu, Prasad and Rakesh. Sandeep is shorter than Kiran but taller than Rakesh. Madhu is tallest. Prasad is a little shorter than Kiran and little taller than Sandeep.
1.Who is the shortest?
(a) Rakesh (b) Sandeep (c) Prasad (d) Kiran (e) None of these
2.If they stand in the order of their heights, who
will be in the middle?
(a) Kiran (b) Rakesh (c) Sandeep (d) Prasad (e) None of these
3.If they stand in the order of increasing heights,
who will be the second?
(a) Prasad (b) Sandeep (c) Rakesh (d) Kiran (e) None of these
4.Who is the second tallest?
(a) Sandeep (b) Kiran (c) Prasad (d) Rakesh (e) None of these
5.Who is taller than Anuj but shorter than Mohit?
(a) Kiran (b) Rakesh (c) Sandeep (d)Date Inadequate (e) None
Solution: Let us analyze the question carefully and now, draw a diagram based on analysis made from the question:
First Step: Sandeep is shorter than Kiran but taller than Rakesh.
Second step: Madhu is tallest.
Third step: Prasad is a little shorter than Kiran and little taller than Sandeep.
Now you can answer the above questions easily:
1) Answer for 1st question is (a): Rakesh is shortest.
2) Answer for 2nd question is (d): Prasad will be in the middle.
3) Answer for 3rd question is (b): In the order of increasing heights that is shortest to tallest: Sandeep is second.
4) Answer for 4th question is (b): Kiran is second tallest.
5) Answer for 5th question is (a): Kiran is taller than Prasad but shorter than Madhu.
Example 2:In an examination, Ramesh got more marks than Mahesh but not as many
as Praveen. Praveen got more marks than Danny and Uday. Danny got less marks than Mahesh but his marks are not the lowest in the group. Who is the second in the descending order of marks?
(a) Praveen (b) Uday (c) Ramesh (d) Cannot be determined (e) None of these
Let us simplify it by marks obtained:
From first sentence: Ramesh got more marks than Mahesh but not as many as Praveen.Mahesh < Ramesh < Praveen
From second sentence: Praveen got more marks than Danny and Uday.Danny < Praveen and Uday < Praveen
From third sentence: Danny got less marks than Mahesh but his marks are not the lowest in the group.Danny < Mahesh
As, given Danny is not the lowest in the group. Then obviously it will be Uday. So, the order would be:Uday < Danny < Mahesh < Ramesh < Praveen
In the descending order Raj comes second.
