Answer 2

Heya friend here's an answer :-..........❤......

So ATQ

Sp = Rs. 495
Profit % = 10

So now Cp = sp×100/100+P%
=> 495×100/100+10%
=> 495×100/110
=> 495×10/11
=> 450

Now the Cp is Rs. 450
_______________________________

Verification:-

Now let the Cp be Rs. 450 and P% is 10 and let's find out the Sp

Sp = Cp×(100+p%)/100
=> 450×(100+10%)/100
=> 450×110/100
=> 45×11
=> 495

So now we get the Sp = Rs. 495 and it is equal to the Sp given in the question so it means our answer is correct.
