Question 9

If two LED TVs and one mobile phone cost ₹31,000, while two mobile phones and one LED TV cost ₹35,000, then the value of one mobile phone is:

Solution

Let the price of an LED be ₹x and the price of a mobile phone be ₹y.

2x + y = 31000

x + 2y = 35000

On solving both equations, we get y = 13000

Hence, the price of a mobile phone is ₹13000.
