Answers:

1.2

Total marks = 75 ×. 52 + 75 × .6 + 75 × .88 + 200 × .59 +

120 × .65 + 150 × .68

= 39 + 45 + 66 + 118 + 78 + 102 = 448

2. 3

Average = 75/6 (.52 + .80 + .56 + .60 + .64 + .76)

= (75 * 3.88)/6

= 48.5%

3. 5

Total marks = 45 + 54 + 42 + 142 + 66 + 84 = 433

Required percentage = 433/695 × 100 = 62.3%

4. 4

CBio = 0.75 × 64 = 48

AEng = 150 × 0.68 = 102

Required percentage = 48/102 × 100 = 47%

5. 1

Difference = 75/100 {(64 + 76 + 60) – (76 + 64 + 48)}

= 75/100 * 12 = 9

6. 5

Absolute value is not given

7. 3

Export > 2 × Import

Export/Import > 2

Which is true for 2010, 2013 and 2015

8. 2

As ration in both years are same we can find import

Import = Export/1.2 = 150/1.2 = 125 crore

9. 2

Required percentage = (2.1 - 2.0)/2.0 * 100 = 5%

10. 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
