Question

a man sold a camera for Rs 1710 at a loss of 5% at what price should he sell the camera in order to gain 5% .

Answer 1

In first
SP=Rs 1710
Loss%=5%
CP={100/(100-loss%)×SP}
= Rs {100/(100-5)×1710 }
= Rs {100/95×1710}
= Rs 1800

In second
CP=1800
Gain%=5%
SP ={(100+gain%)/100×CP }
=Rs {/(100+5)/100×1800}
=Rs {105/100×1800}
=Rs 1890
