If two mixers and one T.V cost Rs. 7000. While two T.V s and one mixer...
Explanation:
Let the cost of one mixer be x and the cost of one TV be y.
- From the given information, we have:
2x + y = 7000 ...(i) (Two mixers and one TV cost Rs. 7000)
2y + x = 9800 ...(ii) (Two TVs and one mixer cost Rs. 9800)
Solving the above two equations:
- Multiplying equation (i) by 2, we get:
4x + 2y = 14000
- Subtracting equation (ii) from the above equation, we get:
3x = 4200
- Dividing by 3 on both sides, we get:
x = 1400
- Substituting the value of x in equation (i), we get:
2(1400) + y = 7000
2800 + y = 7000
y = 7000 - 2800
y = 4200
Hence, the cost of one TV is Rs. 4200. Option C is correct.
Let the cost of one mixer be x and the cost of one TV be y.
- From the given information, we have:
2x + y = 7000 ...(i) (Two mixers and one TV cost Rs. 7000)
2y + x = 9800 ...(ii) (Two TVs and one mixer cost Rs. 9800)
Solving the above two equations:
- Multiplying equation (i) by 2, we get:
4x + 2y = 14000
- Subtracting equation (ii) from the above equation, we get:
3x = 4200
- Dividing by 3 on both sides, we get:
x = 1400
- Substituting the value of x in equation (i), we get:
2(1400) + y = 7000
2800 + y = 7000
y = 7000 - 2800
y = 4200
Hence, the cost of one TV is Rs. 4200. Option C is correct.
