Given:
- Cost price of two laptops is the same
- One laptop is sold at a profit of 15%
- Selling price of another laptop is Rs. 3400 more than the first one
- Net profit is 20%

To find: Cost price of each laptop

Let's assume the cost price of each laptop to be x.

Profit from the first laptop: 15% of x = 0.15x

Selling price of the first laptop: x + 0.15x = 1.15x

Selling price of the second laptop: 1.15x + Rs. 3400

Total profit from both laptops: 20% of (2x + Rs. 3400) = 0.2(2x + Rs. 3400)

According to the given information, the total profit from both laptops is the sum of profit from each laptop. So,

0.15x + (1.15x + Rs. 3400) - 2x = 0.2(2x + Rs. 3400)

Simplifying this equation, we get

0.1x = Rs. 3400

x = Rs. 34000

Therefore, the cost price of each laptop is Rs. 34000.

Hence, option D is the correct answer.
