Question

11. If SP=Rs. 77 and gain=10%, then find the CP​

Answer 1

Answer:

Rs.70=CP

Step-by-step explanation:

Look friend gain 10% means Base is always CP so 100%=CP

and you gained 10% on CP means 110%=SP

:-10%=1/10

so 10=CP

and in this case gain is given so add 1 and 10 so 11=SP

10=CP

11=77

Therefore=CP=70 Rs.

Cross Check 70*110/100=77

This was the easiest method hope its simple good luck.
