A confectioner sells the milk after mixing some water in it at the same rate at which he bought . If he gains 25 % in this way , the quantity of watey mixed with per litre of milk

The answer is 4 : 1     (Ratio of  Milk to Water)

Step-by-step explanation:

Let cost price of the 1 litre of milk be X

selling price to be X +25% of X

cost price = 100/125

= 4/5

;. ratio of milk to water = 4/5 : 1/5 = 4 : 1

therefore, for every 4 litres of milk, one litre of water is added.

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )
