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

Explanation

1.  The last place team (8th position) gets Rs. 4000.

2. The prize money increases by the same amount for each higher position.

3. There are 8 teams, so we need to find the increase in prize money per position.

4. Let's assume the increase per position is x.

5. The 7th position team gets Rs. 4000 + x = ?

6. The 6th position team gets Rs. 4000 + 2x = ?

7. ...

8. The 1st position team gets Rs. 4000 + 7x = ?

We know the total prize money is Rs. 60,000. Let's add up the prize money for each position:
Rs. 4000 + (Rs. 4000 + x) + (Rs. 4000 + 2x) + ... + (Rs. 4000 + 7x) = Rs. 60,000
Combine like terms:
8(Rs. 4000) + 28x = Rs. 60,000
Simplify:
Rs. 32,000 + 28x = Rs. 60,000
Subtract Rs. 32,000 from both sides:
28x = Rs. 28,000
Divide by 28:
x = Rs. 1000
Now we know the increase per position is Rs. 1000.
The 1st position team gets:
Rs. 4000 + 7x = Rs. 4000 + 7(Rs. 1000) = Rs. 4000 + Rs. 7000 = Rs. 11,000
