Answers:
1) Option: 2
Total marks = 75 ×. 52 + 75 × .6 + 75 × .88 + 200 × .59 +
120 × .65 + 150 × .68
= 39 + 45 + 66 + 118 + 78 + 102 = 448
2) Option: 3
Average = 75/6 (.52 + .80 + .56 + .60 + .64 + .76)
= (75 * 3.88)/6
= 48.5%
3) Option: 5
Total marks = 45 + 54 + 42 + 142 + 66 + 84 = 433
Required percentage = 433/695 × 100 = 62.3%
4) Option: 4
CBio = 0.75 × 64 = 48
AEng = 150 × 0.68 = 102
Required percentage = 48/102 × 100 = 47%
5) Option: 1
Difference = 75/100 {(64 + 76 + 60) – (76 + 64 + 48)}
= 75/100 * 12 = 9
6) Option: 5
Absolute value is not given
7) Option: 3
Export > 2 × Import
Export/Import > 2
Which is true for 2010, 2013 and 2015
8) Option: 2
As ration in both years are same we can find import
Import = Export/1.2 = 150/1.2 = 125 crore
9) Option: 2
Required percentage = (2.1 - 2.0)/2.0 * 100 = 5%
10) Option: 2
E/I = 2.8
After change, E1 = 0.75E
I1 = 1.5I
Ratio E1/I1 = 0.75E/1.5I = 0.75/1.5 * 2.8 = 1.4
