A sales agent earns 3% commission on laptops priced at ₹40,000 each and 8% commission on printers priced at ₹8,000 each. If in a week he sells 4 laptops and 10 printers, what is his total commission for 5 such weeks?

The correct option is ₹56,000.

Let's calculate the sales agent's total commission step-by-step.

Step 1: Calculate commission per laptop and printer
Price of one laptop = ₹40,000
Commission rate on laptops = 3%
Commission on one laptop = 3% of ₹40,000

$\text{Commission per laptop}=\frac{3}{100}\times 40000=1200$

Price of one printer = ₹8,000
Commission rate on printers = 8%
Commission on one printer = 8% of ₹8,000

$\text{Commission per printer}=\frac{8}{100}\times 8000=640$

Step 2: Calculate total commission earned in 1 week
In one week, he sells 4 laptops and 10 printers.
Commission from laptops in 1 week = 4 × ₹1,200 = ₹4,800
Commission from printers in 1 week = 10 × ₹640 = ₹6,400

$\text{Total commission for 1 week}=4800+6400=11200$

Step 3: Calculate total commission earned for 5 weeks
To find his total earnings over 5 such weeks, we multiply the weekly commission by 5.

$\text{Total commission for 5 weeks}=5\times 11200=56000$

Thus, his total commission for 5 weeks is ₹56,000.
