Answers
Given : profit made by selling 60 alkaline battery each at Rs. 30 dealer makes a profit equivalent to the cost of 15 of them
To find : Cost Price of an alkaline battery
Solution:
Missing information : Sold each battery at Rs 30
Let say Cost Price of alkaline battery = C
then Cost Price of 15 alkaline battery = 15C
Cost Price of 60 Alkaline battery = 60C
Sold Battery ech at Rs 30
Selling Price of 60 alkaline battery = 60 * 30 = Rs 1800
Profit = 1800 - 60C
Profit = 15C
1800 - 60C = 15C
=> 120 - 4C = C
=> 5C = 120
=> C = 24
cost price of an alkaline battery = Rs 24
