Answer Key

1. (d) 2. (b) 3. (c) 4. (a) 5. (e) 6. (d) 7. (a) 8. (b) 9. (a) 10. (e)


1. (D)

2. (B)

3. (C)

Maximum difference is 5 Lakh  tonnes for three companies C,D and E. So our answer should be the company for which the production is least in 1996. Because to calculate the % increase or decrease our denominator is the production in 1996.

4. (A)

5. (E)

You should not calculate all the values to get the answer. You can decide by mere visual observation. For D & E both the average production is maximum.

6. (D) We don’t know, how many companies belongs to the category called “others” and its volume of sales. So we can’t determine which company has the lowest unit sale price.

7. (A) If we assume the total sales be 100 in the first year, IBM’s sales would go up by 50%(From 28 to 42) contributing an increase of 14 to the total sales value.

Similarly, apple’s increase of 15% would contribute an increase of 2.1 to the sales value. The net change would be 14+2.1= 16.1 on 100.

8. (B) IBM accounts for 28% of the share by value and 10% of the share by volume.

9. (A) Percentage increase of A from 1992 to 1993

10. (E)
