A furniture when sold for Rs. 125280 gives a loss of 13% to the seller who sells it. Calculate his loss or gain %, if he sells it for 162000.

12.5%

    Loss of 13% ⇒ 87% of cost price = 125280

                          1% of cost price   = \(\frac{125280}{87}\) 

                                100% of C. P. =  144000

    Gain = 162000 - 144000 = 18000

    Gain% =  \(\frac{18000}{144000}\) × 100 = 12.5%
