ANSWERS
1. (1) Profit of company A = 3.5 – 2.25 = 1.25
Profit of company C = 2.5 – 2 = 0.5
Profit of company D = 4.25 – 3.5 = 0.75
Profit of company E = 3.75 – 2.5 = 1.25
Required ratio = (1.25 + 0.5) : (0.75 + 1.25) = 7 : 8 = 14 : 16

2. (3) Required average = 13.75/5 crores = 27500000

3. (2) Profit percentage of company A = (1.25/2.25)100 = 55.55
Profit percentage of company D = (0.75/3.5)100 = 21.42
Required difference = 34.13

4. (3) Required percentage = (2.5/3.5)100 = 71.42

5. (2) Required average = 71.25/5 = 34500000

6. (5) Required value = 2% of 6500 =130

7. (3) Required percentage = (11/13)100 = 85

8. (4) Required number of students = (20 + 26 + 17)% of
6500 = 63% of 6500 = 4095

9. (4) Required ratio = 24 : 17

10. (1) Required percentage = 26/20 * 100 = 130

11. (2) From the observations, we can say that maximum percentage increase was from June to Aug.

12. (1) Required Percentage = 440/420 * 100

13. (5) Required Percentage = (460+480)/1000 * 100

14. (3) Average = 2200/5

15. (3) 85% marks = 425. The student received less than 425 marks in Apr (420) and June (400) only
