Question

A shopkeeper bought locks at the rate of 8 locks for rupees 34 and sold them at the rate of 12 locks for rupees 57 calculate his gain percent
​

Answer 1

Answer:

11.7%

Step-by-step explanation:

CP of each lock : ₹34/8

SP of each lock : ₹57/12

gain = SP - CP

gain = 57/12 - 34/8=12/24 =1/2

gain% = gain *100/ CP

gain% = 1/2*100/34*8

gain % = 11.7%
