Answers of above questions:

Solution:

1. Total sale of branch B2 = 75 + 65 = 140
Total sale of branch B4 = 85 + 95 = 180
Total = 140 + 180 = 320

2. Sale of branch B1 in 2001 = 64 * (1/2) = 105
Sale of branch B6 in 2000 = 70
Ratio = 105/70 = 3:2

3. Total sale of all branches in 2001 = 105 + 65 + 110 + 95 + 95 + 80 = 550
Average = 550 / 6 = 91.66

4. Total sale of branch B6 = 70 + 80 = 150
Total sale of branch B3 = 95 + 110 = 205
Percentage = (150/205) * 100 = 73.17

5. Average sale of B1, B2 and B3 in 2001 = (105 + 65 + 110)/3 = 280/3
Average sale of B1, B3 and B6 in 2000 = (80 + 95 + 70)/3 = 245/3
Percentage = (245/280) * 100 = 87.50

6. Total production = 35 + 40 + 60 + 45 + 65 + 50 + 75 + 80 = 450
Average production = 450 / 8 = 56.25
So production in 1997, 1999, 2000 and 2001 is more than average.

7. Average production of 1996 and 1997 = (40 + 60)/2 = 50
This is equal to average production of 2005 and 2000 = (25 + 75)/2 = 50

8. Production in 1997 = 60
Production in 1998 = 45
Decline in production = 60 - 45 = 15
% decline = (15/60)*100 = 25%

9. Percentage increase in production from previous year is highest in 1996.

10. Production in 2002 = 80
Production in 1995 = 25
Increase in production = 55
% increase in production = (55/25) * 100 = 220%
