Question

A man sold 20articles for rs. 60 and gained 20%.how many articles did he buy for rs. 60

Answer 1

Answer: 12 articles

Step-by-step explanation:

SP of 20 articles for a man = ₹60

His gain% = 20%

CP = 100/(100+gain%)*SP

= 100/120*60 = ₹50

CP of 20 articles = ₹50

CP of 1 article = ₹50/20 = ₹2.5

Therefore number of articles bought for Rs 60 = 60/2.5 = 60/25*10 = 12 articles
