दो मिक्सर और एक टीवी की कीमत ₹7,000 है, जबकि दो टीवी और मिक्सर की कीमत ₹9,800 है। एक टीवी की कीमत कितनी होगी?
Detailed Solution & Logic
Correct Answer:
Rs 4,200
Let the price of one mixer be M and one TV be T
Equation 1: 2M + T = 7000
Equation 2: M + 2T = 9800
From equation 1: T = 7000 - 2M
Substitute in equation 2: M + 2(7000 - 2M) = 9800
M + 14000 - 4M = 9800
-3M + 14000 = 9800
-3M = 9800 - 14000 = -4200
M = 1400
Now, T = $ 7000 - 2 \times 1400 = 7000 - 2800 = 4200 $
T = 4200
