Answers & Solutions
1 .
Answer : Option B
Explanation :
Total strength of institute A, B & C in 2003 = 700 + 600 + 720 = 2020 Total strength of institutes E, F & G in 2005 = 750 + 560 + 750 = 2060 ∴ ratio =2020 : 2060 = 202:206 = 101:103
2 .
Answer : Option D
Explanation :
Total students in institute B = 640 + 600 + 620 + 660 + 760 + 740 + 700 = 4720 60% of 4720 = 2832 Average = $2832 \over 7$ = 404.77 or 405.
3 .
Answer : Option A
Explanation :
Strength of students passed in 2002 from all the institute together = 750 + 640 + 680 + 780 + 740 + 620 + 650 = 4860 70% of 4860 = 3402.
4 .

Strength of Institute F, in 2004 = 640 Total strength in institute F = 620 + 580 + 640 + 560 + 650 + 630 + 660 = 4340 $640\over4340$ x 100 = 14.75%
5 .
Answer : Option C
