Question

Find SP of an article, whose CP is ₹20000 when gain is 20%​

Answer 1

Answer:

Step-by-step explanation:

Let CP =x=x, so S.P =1.2x

When CP is Rs. 100 less,

CP=x−100

SP=1.2x−100

Now,  

1.2x−100=1.24×(x−100)

On solving , we get

x=600

CP=Rs.600

Answer 2

ANSWER

Let CP =x=x, so S.P =1.2x

When CP is Rs. 100 less,

CP=x−10

SP=1.2x−100

Now,

1.2x−100=1.24×(x−100

On solving , we get

x=60

CP=Rs.600
