Percentage increase in average marks in social Science in 1996 over the previous year = 14.28%

Percentage increase on average marks in Biology in 1996 over the previous year = 20%

Difference = 20% - 14.28% = 5.72%

One of the men spent 2517 – 1378 = 1139, he is Aman. This is the only possibility as we add Rs. 1378 even to the least amount Rs. 1193, we will not be able to satisfy all the conditions given simultaneously.

So, the table obtained is:

Raman	Aman	Dev	Sanjay	Kamal
2234	1139	1139	1340	2517

Direction for questions 9 to 12:

Coach Rahul sat with the score cards of Indian players from the 3 games in a one-day cricket tournament where the same set of players played for India and all the major batsmen got out. Rahul summarized the batting performance through three diagrams, one for each game. In each diagram the three outer triangles communicate the number of runs scored by the three top scorers from India, where K, R, S, V and Y represent Krunal, Rohit, Sanjay, Virat and Yogesh respectively. The Middle triangle in each diagram denotes the percentage of total score that was scored by the top three Indian scorers in that game.

Y scored 127 in G1 and G3. V scored 130 in G1 itself.

K's mas score could be 28 + 51 + 48 = 127

R's mas score could be 49 + 55 + 22 = 126

S's mas score could be 75 + 50 + 22 = 147

Only R definitely scored less than Y.

Hence, option 2.
