Question

Two mixers and one TV cost ₹7,000, while two TVs and one mixer cost ₹9,800. The value of one TV is:

• A. ₹3600
• B. ₹4600
• C. ₹3200
• D. ₹4200

Answer 1

Answer:

D. ₹4200

Let:

• Cost of one mixer = (M)

• Cost of one TV = (T)

Given:

2M + T = 7000

M + 2T = 9800

From the first equation:

T = 7000 - 2M

Substitute into the second equation:

M+2(7000-2M)=9800

M + 14000 - 4M = 9800
-3M = -4200
M = 1400

Now,

T = 7000 - 2(1400)
T = 7000 - 2800 = 4200

Value of one TV = ₹4200
