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 .

Answer : Option D

Explanation :

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

Explanation :

Total students in 2006 from all the institute together = 740 + 760 + 690 + 780 + 650 + 680 = 5090 Total students in 2008 from all the institute together. = 780 + 700 + 660 + 840 + 720 + 660 + 740 = 5100 ∴ Difference = 5100 – 5090 = 10

8 .

Answer : Option B

Total investment of A&B in 2002 = 40+70 = 110 Total investment of A&B in 2005 = 50+70 = 120 Therefore, $120-110\over110$ x 100 = $10\over110$ x 100 = 9.09% increase

9 .

Answer : Option A

Total investment of A in 2001, 2002 & 2003 = 60 + 40 + 50 = 150 Total investment of B in 2001, 2002 & 2003 = 50 + 70 + 60 = 180 ∴ Ratio = 150 : 180 = 15:18 = 5:6

10 .

Answer : Option D

Explanation :

Investment of B in 2003 = 60 Total investment of B for all the years together = 50 + 70 + 60 + 80 + 50 + 50 + 60 = 420 Therefore, $60\over 420$ x 100 = 14% (approx.)
