- Let's denote the cost of one mixer as M and the cost of one TV as T.

- According to the problem, we have two equations:

- 2M + T = 500 (equation 1)

- 2T + M = 700 (equation 2)

- From equation 1, rearrange to find T: T = 500 - 2M.

- Substitute this in equation 2: 2(500 - 2M) + M = 700.

- Simplifying, gives 1000 - 4M + M = 700.

- Further simplify to get: -3M = -300, thus M = 100.

- Substitute M = 100 back into equation 1 to find T: 2(100) + T = 500, so T = 300.

- Therefore, the cost of one TV is Rs300.

- Option 3: Rs300 is correct.
