Question
Two mixers and one TV cost ₹7,000, while two TVs and
one mixer cost ₹9,800. The value of one TV is:Solution
Let: Mixer = M, TV = T Equations: 2M + T = 7000 M + 2T = 9800 From (1): 2M + T = 7000 → Multiply by 1 From (2): M + 2T = 9800 → Multiply by 2 → 2M + 4T = 19,600 Now subtract: (2M + 4T) − (2M + T) = 19,600 − 7000 → 3T = 12,600 ⇒ T = 4200
