Question

A man buy 100 diwali cards for 850 and sold 10 for 136 find gain percentage

Answer 1

CP of 100 cards = 850
CP of 1 card = 850/100 = 8.5
SP of 10 cards = 136
SP of 1 card = 136/10 = 13.6
Profit = SP - CP
=> 13.6 - 8.5
=> 5.1
Profit % = ( profit / CP × 100)%
=> ( 5.1/8.5 × 100)
=> ( 510/8.5 )
=> 60 %
hence the required profit% is 60% .
