Correct Option - 4
Detailed Solution:If S4 is ranked 6th and S2 is ranked 5th, we have
O > O > O > O > S2 > S4 > O
In this case, S3 will rank the highest and thus S5 will rank the least. We have, S3 > O > O > O > S2 > S4 > S5
Also, the order S7 > S1 > S2 will be maintained The possible arrangements are
S3 > S6 > S7 > S1 > S2 > S4 > S5
or S3 > S7 > S6 > S1 > S2 > S4 > S5 or S3 > S7 > S1 > S6 > S2 > S4 > S5
Thus, option (d), i.e., S6 can be ranked third or fourth is true.

the highest average is Rs. 136
Using the data from above question, the lowest average is Rs. 100.
We get the following table of earnings:
Persons | Win Total | Average |
P | 36 * 150 + 14 * 100 = 6800 | 136 |
Q | 34 * 150 + 21 * 100 = 7200 | 131 |
R | 23 * 150 + 36 * 100 = 6850 | 116 |
S | 30 * 150 + 30 * 100 = 6000 | 100 |
Now we can see that the largest difference
= Maximum – Minimum = Rs. 7500 – Rs. 6800
= Rs. 700
IITs = 60; IIMS = 40
