__Answers: __

**Ans (1 - 5)**

1. (3) Export of Company A in 1993 = Rs 2.25 crores

( Given - graph shows the ratio of export to import)

then A's ratio of export : import = 1.5 or 15/10

So 2.25/x = 15/10

Hence, Import of Company A in the year 1993 = 1.5 crore

2. (4) Can’t Say

3. (3) Exp of Company A in the year 1991

E/I = 2/1

E/2 = 2/I

E = 4 Crore

Exp of Company B in the year 1991

E/I = 3/1

E/3 = 3/1

E = 9 Crore Req Ratio 4 : 9

4. (4) Req. Percentage = (3 - 2.5)/2.5 * 100 = 20%

5. (5) Data Inadequate Solutions

**Ans (6-10)**

Total Number of Employees in company A = x * 20/100 = 880 = 4400

Total Number of Employees in company B = x * 24/100 = 864 = 3600

6. (3) Total number of Employees of Software Developers in company A = 26/100 * 4400 = 1144

Total number of Employees of Software Developers in company B = 28/100 * 3600 = 1008

Required Difference = 1144 - 1008 = 136

7. (2)

8. (2) Ratio of the number of Accountants of company A to B = 528 : 396 = 4:3

9. (3) Required Percentage = (864 - 324)/324 * 100 = 166%

10. (4) Required Percentage = (770/4400) * 100 = 17.5% = 17%

**Ans (11 - 15)**

11. (3) Total number of Girls who appeared in 2007 = 1000/100 * 36 = 360

Total number of Girls who passed in 2007 = 500/100 * 55 = 275 Total number of Girls who failed = 360 – 275 = 85

12. (1) Total number of girls passed in 2009 = 288

Total number of boys failed in 2009 = 770 – 512 = 258

Total sum = 288 + 258 = 546

13. (5) Total number of boys who appeared in all 5 years = 2925

Total number of boys who passed in all 5 years = 1739

Total difference = 2925 – 1739 = 1186

14. (3) Required Ratio = 770 : 330 = 7:3

15. (2) Number of boys passed in 2005 = 480

Number of girls appeared in 2006 = 400

Req % = (480 - 400)/400 * 100 = 20
