Detailed Solution

Given that,
S.P. = Rs. 24480
Loss = 4%
We have the following formulas,
S.P=selling price.
C.P=cost price.
Gain=S.P-C.P

G a i n % = S . P − C . P C . P × 100

Loss=C.P-S.P

L o s s % = C . P − S . P C . P × 100

C.P of the computer at a loss of 4% is,

= 100 100 − 4 × 24480 = 10096 × 24480 = 25500

The S.P of a computer at a gain of 4% is,

= 100 + 4 100 × 25500 = 104100 × 25500 = 104 × 255 = 26520

The S.P of a computer at a gain of 4% is Rs 26520.
Therefore, the correct answer is option 2.
