The price difference of 4 tablets and 3 mobile phones is Rs. 34000. Ravi buys 3 tablets and a mobile phone for Rs. 32000. What is the price of 2 tablets and 3 mobile phones? Correct Answer Rs. 26000

Let the prices of tablet and mobile phone be x and y respectively,

4x - 3y = 34000   ---- (i)

3x + y = 32000   ---- (ii)

Multiplying equation (ii) by 3 and adding it to equation (i)

⇒ (4x + 9x) + (-3y + 3y) = (34000 + 96000)

⇒ 13x = 130000

⇒ x = 10000

Putting the value of x in equation (ii),

⇒ y = 32000 - 3(10000)

⇒ y = 2000

∴ Price of 2 tablets and 3 mobile phones = 2(10000) + 3(2000) = Rs. 26000
