Question

the selling price of a TV set is equal to 6 by 5 of its cost price find the gain percent​

Answer 1

GIVEN :-

Selling Price = SP

Cost Price = CP

SP ( of a TV ) = 6/5 of its CP

SP = 6/5 × CP (E.q. 01)

TO FIND :- Gain Percent

SOLUTION :-

We know That Gain occurs when

SP > CP => Gain = SP - CP

Gain = 6/5 CP - CP (FROM EQ.01)

=> Gain = (6CP - 5CP)/5

=> Gain = CP/5

Now we can use Formula to Find the gain %

Gain % = Gain/CP × 100

= CP/5 /CP × 100

= CP/5 ÷ CP × 100

= CP/5 × 1/CP × 100

= 1/5 × 100

= 25%

Hence The gain% is 25% in this case. (ANS).

The gain percent of TV is 25%

Answer 2

Greetings..!

Let Cost price = Rs x

Then,S.P = Rs 6x/5

Then gain = sp - cp = Rs x/5

So, gain percent = gain/cp *100 = ( x/5)*(1/x)*100 = 20%

Answer : Hence, gain percent = 20%
