1.	A man sold two TV sets for ₹12,480 each.On one he gains 20% and on the other he loses 20%.How much does he gain or loss percent on the whole transaction
Answer» Answer Selling price of two T.V. sets =2400 RS. each Let cost price of a T.V. sets on which he gain 20% be X Rs and another T.V. sets on which he lost 20% be Y Rs. SOLVING for T.V. sets on which he gain We know that, Selling price=Cost price+profit ⇒2400=X+20% of X ⇒2400=X+0.2X ⇒2400=1.2X ⇒X=1.22400 ∴X=2000 Rs Now, Solving for T.V. sets on which he loss We know that, Selling price=Cost price−loss ⇒2400=Y−20% of Y ⇒2400=Y−0.2Y ⇒2400=0.8Y ⇒Y=0.82400 ∴Y=3000 Rs Now, Total Cost price=X+Y=2000+3000=5000 Rs and Total Selling price=2×2400=4800 Rs Since Selling price So, In whole transaction, there is a Loss of 5000−4800=200 R Hope it helps Please mark me as brainliest THANKS :)

Answer

Selling price of two T.V. sets =2400 RS. each

Let cost price of a T.V. sets on which he gain 20% be X Rs

and another T.V. sets on which he lost 20% be Y Rs.

SOLVING for T.V. sets on which he gain

We know that, Selling price=Cost price+profit

⇒2400=X+20% of X

⇒2400=X+0.2X

⇒2400=1.2X

⇒X=1.22400

∴X=2000 Rs

Now, Solving for T.V. sets on which he loss

We know that, Selling price=Cost price−loss

⇒2400=Y−20% of Y

⇒2400=Y−0.2Y

⇒2400=0.8Y

⇒Y=0.82400

∴Y=3000 Rs

Now, Total Cost price=X+Y=2000+3000=5000 Rs

and Total Selling price=2×2400=4800 Rs

Since Selling price

So, In whole transaction, there is a Loss of 5000−4800=200 R
