Answers:
Solutions (1-5)
Total Profit = 60 Crore

According to Questions:

Profit of Company B is 20% of the Income of Company C
Let Income of Company C is P
So P x 20% = 16
P = (16 * 100)/100 = 80 Cr.

Income of Company C = 80 Cr

Profit of Company B is also equal to 40% of the Expenses of Company A

Let Expense of Company A is P

So P x 40% = 16
P = (16 * 100)/40 = 40 Cr
Expense of Company A = 40 Cr

1. C. 

2. B. Req % = 24/40 * 100 = 60%

3. E. Req % = (56 - 40)/56 * 100 = 40%

4. A. Total Average Income of the company = 180/3= 60 crore
Total Average Profit of the company = 60/3 = 20 Crore

Req Ratio 60 : 20 = 3 : 1

5. B. In 2006 Profit of company A = 120/100 * 20 = 24 Crore

In 2007 Profit of company A = 120/100 * 24 = 28.8 Crore


6. E.
Let the numerator and denominator be 2x and 5x. Now
(2x + 4)/10 = 1/3
X = 3.
Required sum = 2x + 5x = 7x = 21

7. A.
Required percentage = (750000 - 700000)/700000 * 100 = 7.14%

8. C.
Number of books to be removed = 19 5 +1  = 96

9. B.
Number of arrangements = 3! *  6! = 4320

10. C.
Total score of students = 3 * 90 + 9 * 80 + 4 * 70 + 4 * 60 = 1510
Required average = 1510/20  =  75.5
