Question

By selling a TV set for 25000,a dealer gains of its cost price. Find his gain and cost price

Answer 1

Answer:

Let the C.P of the TV = x when x is in Rs.

∴ 25% profit = x×

100

25

=

4

x

and the S.P. = x+

4

x

=

4

5x

.

In the second case, by the given condition, the profit is 25% of

4

5x

=

4

5x

×

100

25

=

16

5x

.

∴ The difference in profits =

16

5x

−

4

x

=

16

x

.

Now 5% of the C.P. + Rs. 100= x×

100

5

+100=

20

x

+100.

So, by the given condition, we have

16

x

=

20

x

+100

⇒

16

x

−

20

x

=100

⇒

80

x

=100

⇒x= Rs. 8000

So,the cost price of the TV = Rs. 8000
