Ans. Let Cost Price [CP]= y
Selling Price [SP] = 1140
Loss % = 5%
We Know
\({SP} =[{ {(100- Loss\%)\over 100 } \times CP}]\)
=> \(1140 = [{{(100-5)\over 100} \times y }]\)
=> \(1140 = {95\over 100} \times y \)
=> \( y = {{1140 \times100}\over 95} = 1200 \)
Cost Price = Rs. 1200
Gain % = 5 %
New SP = \({1200 \times 105 \over 100 } = 1260 \)
To Gain 5% He Should Sell For Rs. 1260
