24-27) there were 3 questions on venn diagrams (like 20 spek eng,30 speak hindi 3 speak both and so on….)

28-32)5 questions based on 1 piechart (data interpretation).

CRITICAL REASONING: ( 3 puzzles with 4 questions each)
1) Some seating arrangement problem like there were 6 people A, B, C, D, E, F sitting in a table they all are agricultural minister, health minister, education minister and so on. The hints proceed like this. 1) A sits 2 seats away from D. 2) agricultural minister cannot sit near health minister. And some 3 more hints (I don’t remember) using the hints given in the question U have to trace out their seating position in a round table and have to answer 5 questions based on it.
2) all P’s are Q’s, some R’s are Q’s , all P’s are E’s…..so on. With these hints u can draw a venn digram and answer the following 5 questions. All the questions are from GRE Barron model papers (12 th ,13 th edition) so just solve all those. (Just mug up the answers.)
3) barons gre 12 edition page 496 Ashland is north of east liverpool
