Solution:

1). In 2001, from the Rest states there were 19% of the total students appearing whereas in 2002, 13% of the total students appearing. And also, the total no. of students in 2001 was more than that in 2002. So, the difference between two years of Rest states represents the maximum difference.

2). No. of students appearing from Bihar in 2002 = 20%
Of 2.40 = 48000
No. of students appearing from WB in 2001
= 20% of 2.50 = 50000
Reqd% = (48000 / 50000) ร 100 = 96%

3). Total no. of students appearing from Bihar and UP together in 2001 = 30% of 2.50 lakhs โ x% of 2.40 lakhs in 2001 of two states. As far as the value of โxโ in concerned it must be more than 30%. On this basis we eliminate options a) and b). Now, we can eliminate option c) also because it is giving a very large value. In the remaining two options, we find that d) is satisfying the criteria

4). Reqd % = (30000 / 240000) ร 100 = 12.50%

5). Reqd % = [(18% of 2.50) / (23% of 2.40)] ร 100 โ 80%

6). Avg marks of girl students in school N
= (70 + 80 + 60 + 62 + 58) / 5 = (330 / 5) = 66
Avg marks of girl students in school Q
= (68 + 82 + 40 + 50 + 50) / 5 = (290 / 5) = 58
Reqd difference = 66 โ 58 = 8

7). Total marks of the boys from school Q = 75(73 + 85 + 50 + 60 + 60)
= 75 ร 328
Total marks of the girls from school Q = 25(68 + 82 + 40 + 50 + 50)
= 25 ร 290
Reqd difference = 25(3 ร 328 โ 290)
= 25 ร 694 = 17350

9). Total marks obtained by school P students in Computer and economics
= (80 + 82) ร 80 + (85 + 85) ร 20 = 16360
Percentage marks obtained by school P students in Computer and economics
= (16360 / 20000) ร 100 = 81.8%
Total marks obtained by school Q students in Computer and Economics
= (73 + 85) ร 75 + (68 + 82) ร 25 = 11850 + 3750 = 15600
Percentage marks obtained by school Q students in Computer and Economics
= (15600 / 20000) ร 100 = 78%
Reqd difference = 81.8 โ 78 = 3.8%

10). Average marks from school M in computer
= (80 ร 60 + 70 ร 40) / 100 = 76
Similarly, N = 81.4, P = 82.6, Q = 84.25, R = 78.52
Average of all school taken together = (76 + 81.4 + 82.6 + 84.25 + 78.52) / 5 โ 80.55
Reqd ratio = 3 : 2
