(a) 1652 (b) 777 (c) 1155 (d) 1040 (e) None of these.
Ans: (c)
Tricky question: The normal tendency is to find the difference between the last bill no of March and the first bill no of January for all the four branches and the total will be marked as the answer . This way the total would come to 1151.
But the number of bills raised in any month is the difference between the last bill of the month and the last bill of the previous month.
To answer this question we should take the last bill of December for all the branches and then subtract the same from the last bill of March and that would give the total number of bills raised during this three month period.
The correct answer is —– 417 + 246 + 294 + 198 (respectively for the four branches) totaling 1155.

Mumbai —- Total Sales — 1292488 Total bills raised – 417 Average per bill — 3099.49
Delhi —– Total Sales — 600709 do 246 do — 2441.90

(a) 28% (b) 22% (c) 31% (d) 17% (e) None of these
Ans: (b)
Total sales during the three month period is —– 3110908 (Add the total sales in the previous question)
Total sales of Kolkata branch during the three months period — 688914.
Hence the contribution of Kolkata branch —- 688914/3110908 * 100 = 22%
