Answer:
23.75
Step-by-step explanation:
Ravish bought 100 articles for 4000.
Cost price for 1 article = (4000/100) = 40.
Cost price of 20 articles = 40 * 20 = 800.
He sold 20 of them at a gain of 5%.
Gain = 5% of 800
= (5/100) * 800
= 40.
Selling price of 20 articles = 800 + 40 = 840.
Cost price of 80 articles(100 - 20) = 4000 - 840
= 3200.
It is said that 20% at whole.
Selling price of 100 articles = 4000 + 20% of 4000
= 4000 + (20/100) * 4000
= 4000 + 800
= 4800.
Ravish already sold 20 articles for 840.
Selling price of 80 articles = 4800 - 840
= 3960.
Selling price > Cost price..So, Gain.
Gain = Selling price - Cost price
= 3960 - 3200
= 760.
Gain% = (gain/CP) * 100
= (760/3200) * 100
= 23.75.
Hence, Gain percent = 23.75.
Hope it helps you.
