Question

Raj sold an iteam Rs 6384 and incurred a loss 30%, at what price sold the iteam to have gain a profit of 30%

Answer 1

SP=Rs 6384
Loss%=30
Then,  CP=100/(100-Loss %)×SP
                =100/(100-30)×6384
                =100/70×6384
                =Rs 9120

Again,
Gain%=30%
CP=Rs 9120
Then,  SP=(100+Gain%)/100×CP
                =(100+30)/100×9120
                =130/100×9120
                =Rs 11856

Thanks for asking
