Question

A milkman professes to sell milk at the cost price but gives only 900 ml in place of 1 litre. Find his gain on loss percent.​

Answer 1

Answer:

16.6%

Step-by-step explanation:

Let CP of 1 lit milk = 1 rs

SP of 1 lit of mixture = 1 rs

Gain is 20%

CP of 1 lit of mixture = 100/120*1= 5/6

Ratio of milk and water is

5/6–0:1–5/6 = 5/6:1/6

% age of water in mix = 1/6*100 = 16.6%

Note:

• where sp = selling price
• where cp = cost price
• where rs = rupees
• where * is multiplication(x)
• where % is percentage
