Answer:


1) 1;
Production of company A in 2012

Production of company A in 2013 

∴ Required percentage increase

2) 4;
Required average


3) 2; 
Required percentage

4) 1;
Total production of company A in all the years together
= 450 + 480 + 250 + 375 + 500 + 360 = 2415
Total sales of company B

= ( 240 + 375 + 350 + 350 + 250 + 325) = 1890

∴ Required ratio = 2415 : 1890 = 161:126

5) 2;
Average sales of company A

6) 5; 
Required ratio 

= 400 : 450 = 8:9
