Detailed Solution

Given that,
S.P. = Rs. 21600
Profit = 8% .
We have the following formula:
S.P=selling price.
C.P=cost price.
Gain=S.P-C.P
Gain%= S.P−C.P C.P ×100  
Loss=C.P-S.P
Loss%= C.P−S.P C.P ×100  
We are given that, the S.P of sofa set is Rs 21600 at a gain of 8%.
The C.P of sofa set is
= 100 100+8 ×21600 = 100 108 ×21600 =20000   The correct option is 2.
