Instructions

Directions: Study the following information and answer the following questions: A, B, C, D, E, G, and I are seven friends who study in three different standards, namely 5th, 6th, and 7th, such that not less than two friends study in the same standard. Each friend has a different favourite subject, namely History, Civics, English, Marathi, Hindi, Maths and Economics also but not necessarily in the same order.

A likes Maths and studies in the 5th standard with only one other friend who likes Marathi. I studies with two other friends. Both the friends who study with I like languages (here languages include only Hindi, Marathi and English). D studies in the 6th standard with only one person and does not like Civics. E studies with only one friend. The one who likes History does not study in the 5th or 6th standard. E does not like languages. C does not like English, Hindi or Civics.

Question 8

Who among the following studies in the 7th standard?

Solution

Let us solve the question by the tabular method

A is in 5th standard and likes Maths. So tick the blanks 5th standard and Maths for A and cross the rest of the Maths column.
A studies with only one person who likes Marathi. I studies with two other friends who like languages.D studies in 6th standard with only one person and does not like civics. So tick the 6th standard blank corresponding to D and cross the civics blank for D. E studies with only one friend and doesn't like languages. The one who likes history doesn't study in 5th or 6th standard. D , E study with only one person. D is in 6th standard and E doesn't like languages. The remaining are B , C , G and I. I studies with two more persons who like languages. C doesn't like English and Hindi. So C cannot be I's classmate and can only be A's classmate because E doesn't like languages, C should like Marathi . Hence tick 5th standard and Marathi for C, cross the rest of the Marathi column. Similarly E is D's classmate because E studies with only one person and doesn't like Marathi. So tick 6th standard for E. Finally B and G are I's classmates, hence tick the 7th standard for B,G and I. Now that the standards are set, let's move to the subjects. Since B and G like only the languages and Marathi is already choosen by C, they are left with only two blanks each which are English and Hindi. So cross the rest of the row for B and G. The one who likes history is not in 5th and 6th. In seventh standard B and G like only languages, hence I likes history. Mark history blank of I and cross the rest of the column. Now civics column should be left with one blank , which corresponds to E. Tick the blank corresponding to civics for E and cross the rest of the row . Finally a blank in Economics column corresponding to D is left. Mark it and cross the blanks for other subjects of D's row.
The table should look like below after following the above steps.
