1. c. Rs. 46,000
Let the sales of Pencil, Eraser and Sharpener be denoted by matrix X
Let the unit sale price of Pencil, Eraser and Sharpener be denoted by matrix Y
Now,
Total Revenue = Total sales x Unit sales price
= XY
Hence,
Total revenue of Market A = Rs. 46,000
Total revenue of Market B = Rs. 53,000
2. b. Rs. 53,000
Total revenue of Market B = Rs. 53,000
3. d. Rs. 31,000
Let the unit cost price of Pencil, Eraser and Sharpener be denoted by matrix Z
Now,
Total Cost = Total sales x Unit cost price
= XZ
∴ Total cost of Market A = Rs. 31,000
4. a. (Rs.15, 000, Rs.17, 000)
Thus,
Profit in Market A = Rs. 15,000
Profit in Market B = Rs. 17,000
5. c. Rs. 32,000
Now,
Profit in Market A = Rs. 15,000
Profit in Market B = Rs. 17,000
Gross profit in both market = Rs 15,000 + Rs 17,000
= Rs 32,000
