The cost of an oven is 15% of the cost of TV. The difference between the price of the TV and oven is Rs. 34000. What is the average price of a TV and oven? Correct Answer Rs. 23000

⇒ Average = sum of elements / number of elements

Given,

Let the price of a TV and an oven be Rs. a and Rs. b respectively.

The cost of oven is 15%of cost of TV.

⇒ b = (15/100)a

⇒ b = 3a/20

Given,

The difference between the price of TV and oven is Rs. 34000.

⇒ a - b = 34000

⇒ a - 3a/20 = 34000

⇒ 17a/20 = 34000

⇒ a = 34000 × (20/17)

⇒ a = 40000

The price of a TV = Rs. 40000

⇒ b = (3 × 40000)/20

⇒ b = 6000

The price of an Oven = Rs. 6000

The average price of TV and oven =

= (40000 + 6000)/2

= 23000

The average price of TV and oven is Rs. 23000.
