Explanation

Let's calculate the price of the printer after 3 years, considering an annual depreciation of 4%:

Year 1:

Depreciation = 4% of Rs. 150000 = Rs. 6000

Price after 1 year = Rs. 150000 - Rs. 6000 = Rs. 144000

Year 2:

Depreciation = 4% of Rs. 144000 = Rs. 5760

Price after 2 years = Rs. 144000 - Rs. 5760 = Rs. 138240

Year 3:

Depreciation = 4% of Rs. 138240 = Rs. 5529.60

Price after 3 years = Rs. 138240 - Rs. 5529.60 = Rs. 132710.40

Rounding to the nearest whole number, the price of the printer after 3 years is:

Rs. 132710
