A shopkeeper reduces the price of his goods by 50% at the time of sale. Initially the price was fixed to get a profit of 25% on selling price after allowing 10% cash discount. His approx. % of profit or loss?
Let marked price be 100
10% discount on marked price means selling price is 90.
This selling price is fetching 25% profit, so cost price is 72.
⇒x+25
⇒100x+25x=90×100
⇒125x=90×100
⇒x=72
50% reduction in marked price means actual selling price is 50.
So, CP is 72, SP is 50.
Loss =72−50=22
Percent loss =2272×100=30.55%
So, we will consider it as 30%.
