Read Solution (Total 1)
-
- Existing quantity of milk = Q litre
Added 20 % water = (20/100)Q = 0.2Q litre
Total Mixture = Q+ 0.2Q = 1.2Q litre
Cost Price = 10Q Rs
Selling Price = 1.2Q * 10 = 12Q Rs
Profit = 2Q Rs
Fine = 200 Rs
profit - fine = net profit
Loss = 100 Rs = - 100 Rs net profit
2Q - 200 = - 100
=> 2Q = 100
=> Q = 50
Total Mixture = 1.2Q = 60 Litre
