Question

Reena sold two articles at RS 2970 each. On one she gains 10% and on other she loses 10%.how much does she profit or loss in the whole transaction? Also, find her profit or loss percent in the whole transaction​

Answer 1

Step-by-step explanation:

SP=Rs.840

gain=20%

gain%=

CP

(SP−CP)

×100

20=

CP

(840−CP)

×100

Solving the above equation, we get,

0.20CP+CP=840

CP=

1.2

840

=Rs.700

loss=20%

loss% =

CP

(CP−SP)

×100

20=

CP

(CP−840)

×100

Solving the above equation, we get,

CP−0.20CP=840

CP=

0.8

840

=Rs.1050

Total−CP=700+1050=1750

Total−SP=840+840=1680

loss=1750−1680=Rs.70

loss%=

CP

loss

×100=

1750

70

×100=4%

Answer 2

Answer:

SP of 1st is=2970

gain=10%

Let CP of 1st be x

Then 10%of x+x=2970

10/100x+x=2970

Now it will become :

11x/10=2970

x= (2970*10)/11= 2700 Rs

Profit=270 Rs

Sp of 2nd is also 2970

loss=10%

Let CP of 2nd be y

Then y-10%of y=2970

y-y/10=2970

9y/10=2970

y=3300Rs

Loss= 330Rs

Gain<Loss

so loss is of 60 Rs.
