Solution -
Let,
Total number of articles = 100
CP of 1 article = 1
CP of 100 article = 100
SP of 100 articles = 100 - (100 × 14/100)
= 100 - 14
= 86
He sold 60% of those at a profit of 16.66%.
CP of 60 article = 60
SP of 60 articles = 60 + (60 × 1/6)
= 60 + 10
= 70
CP of 40 articles = 40
SP of 40 articles = SP of 100 articles - SP of 60 articles
= 86 - 70
= 16
loss = CP - SP
= 40 - 16
= 24
Loss percentage = (24/40) × 100
= 60%
Hence,
The correct answer is option (c) 60%.
