Answer 2

Answer:

cp= ₹ 500

Step-by-step explanation:

Let cp be rs x

loss%=( loss/cp)×100

10= loss/x×100

10/100= loss/x

1/10x= loss

loss = x/10

cp=sp- loss

x = 450 - x/10

x+x/10= 450

9x= 4500

x= 4500/9

x=cp= ₹500.

You can prove it also

cp=500

sp=450

then loss = ₹ 50

loss%= (loss/cp)×100

=50/500×100

100/10

=10%
