Question

If SP = Rs 77 and gain = 10% , then find the Cost price.

Answer 1

Answer:

same as that question

Step-by-step explanation:

SP = (100 + Gain%)/100 * C.P.

924 = 100 + 10/100 * C.P.

924 = 110/100 * C.P

C.P = 924 * 10/11

C.P = 9240/11 = 840.

So, the Cost Price C.P = 840.

Answer 2

Let CP = ₹x

Then gain= ₹x×10/100%

=₹x/10

Sp= Cp + gain

=₹x+₹x/10

=₹11x/10

So, 11x/10=77

11x=77×10

11x=770

x=770/11

x=70

So, CP=₹70
