Answer» SP = Rs.720 Loss % = 25 CP \(=\frac{100}{100\,-\,Loss\%}\times SP\) \(=\frac{100}{100\,-\,25}\times 720\) = Rs.960 SP = \(\frac{100\,+\,Gain\%}{100}\times CP\) = \(\frac{100\,+\,25}{100}\times 960\) = Rs.1200

On selling a chair forRs. 720, a man loses 25%. To gain 25% it must be sold for A. Rs.900 B. Rs.1200 C. Rs.1080 D. Rs.1440

Answer»

SP = Rs.720

Loss % = 25

CP \(=\frac{100}{100\,-\,Loss\%}\times SP\)

\(=\frac{100}{100\,-\,25}\times 720\)

= Rs.960

SP = \(\frac{100\,+\,Gain\%}{100}\times CP\)

= \(\frac{100\,+\,25}{100}\times 960\)

= Rs.1200
