Question

dear friends plz answer for this question ​

Answer 1

Answer:

TV price = Rs 20000

Fridge price = Rs 10000

Step-by-step explanation:

Given:

5% profit on TV + 10 % profit on Fridge = Rs 2000-------(i)

10% profit on TV + 5 % loss on Fridge = Rs 1500-------(ii)

To find:

It's written prize but I think it's price .

Price of TV and Fridge

Solution:

let, the price of TV be 100x and Fridge be 100y respectively .

5% profit on TV = 5x

10% profit on Fridge = 10y

From (i) I get,

5x + 10y = 2000

5(x + 2y) = 2000

x + 2y = 400

2x + 4y = 800 ------(1)

From (ii) I get,

10x - 5y = 1500

5(2x - y) = 1500

2x - y = 300 -----(2)

By Eliminating, 1 from 2 , I get,

5y = 500

y = 100

So, x = 200

Therefore, The required price of TV

100x = Rs 20000

and Fridge price

100y = Rs 10000
