a)   4615
b)   4565
c)   4260
d)   4090
e)   4165

1). D)
Total number of students (both male and female) in institute C =2100 x (20 /100) = 420
Total number of science graduates in institute C = 420 x (1/3) =140
Total number of female science graduates in institute C =140 - 32 =108
Total number of female students in institute C =900 x (30/100) =270
Required percentage = (108/270) x 100 = 40%

2). D)
Total number of students (both male and female) in institute A in year 2014
= 2100 x (14/100) x (150/100) = 441
Total number of females in year 2014
=  3 /(3+4) x 441 = (3/7) x 441 =189

3). D)
Required central angle = (360 / 100) x 17 =61.2°

4). C)
Total number of students (both male and female) in institute A, D and E .
=2100x (14+17+25) /100
=2100 x 56/100 =1176
Total number of female students in institute A, D and E = 900 x [(18 + 15 + 15) / 100] = 900 x (48/100) = 432
Total number of male students in institute A, D and E
= 1176 — 432 =744
Required average = 744/3 = 248

5). C)
Number of female students in institute B = 900 x (22/100) =198
The number of male students in institute C = 2100 × (20 / 100) – 900 × (30 / 100)
= 420 —270 =150
Required percentage = (198 - 150) / 150 × 100
=  48/150 x100 = 32

6). C)
Total number of female students in institute A and E together
= 900 x (18 + 15) /100
= 900 x 33 / 100
=297
Total number of students (both male and female) in institute B
= 2100 x 24 / 100
=504
Required difference =504-297 =207

7). C)
? = √3598.9 x [(10008.99)2 / (10009.001)] x 0.4987
= √3600 x [(10009)2 / 10009] x 0.4987
= 60 x 10009 x 0.5 = 30 x 10009 = 300270

8). A)
39.05 x 14.95 — 27.99 x 10.12 = (36 + ?)5
or, 39 x 15 — 28 x 10 = 180 + 5 x (?)
or, 5 x ? = 585 — 280 — 180 = 585 — 460 = 125
? = 125/5 = 25

9). C)
? = 68.25 x 170 + 28 x 16.5 — 125 x 16.5 = 11602.5 + 462 — 2062.5
= 12064.5 — 2062.5 = 10002 = 10000

10). B)
? = 487.582 + 2849.029 — 675.48 — 743.095 = 488 + 2849 — 675 — 743 = 1919 1920

11). E)
? = 12600 — (142 / 100) x 3915 - 2874

= 12600 — 5560 — 2874 = 4166 = 4165
