Solution: 1.c 2.a 3.d 4.e 5.d

1. Average sales of grade 1= (20+40+50+60)/4= 42.5 tonnes
Average sales of grade 2= (40+60+20+110)/4= 57.5 tonnes
Difference= 57.5-42.5= 15 tonnes.

2. Total income of companies A= (75000*20) + (60000*40) = Rs.3900000
Total income of companies C= (75000*50) + (60000*20) = Rs.4950000
Difference= Rs.1050000= Rs. 1.05 million.

3. 3 companies= A, B and D. See the table below.
Company
Grade 1 (tonnes)
Grade 2 (tonnes)
A
20
40
B
40
60
C
50
20
D

110

4. Net income of company A= (75000*20)+(40*60000)= Rs.3900000
  Grade 1 constitutes 38.46% ((150000/3900000)*100)

5. Total production by company D= 60+110= 170 tonnes
Total production by company B= 40+60= 100 tonnes
Total production by company D is 170 % that of company B. (170/100)*100
