In a solution of 45 litres of milk and water, 40% is water. How many litres of milk must be added to become the ratio of milk & water 5 : 3?
Answers
Step-by-step explanation:
45 litre = milk + water
40 %water means milk = 100-40=60%
ratio = milk : water
= 60 : 40
= 3 : 2
= water 40 % of total
= 40×45/100
= 18 litre water
total = 45 - 18 water = 27 litre milk
ratio = 3 : 2 = (×9) 27 : 18
required ratio = 5 : 3
= 5×9 : 3×9
= 45 :27
milk to add = 45 - 27
= 18 litre
therefore, 18 litres of milk must be added to become the ratio of milk and water 5 : 3
Answer:
Step-by-step explanation:
Total = 45L
If 40% is water, water = (45*40)/100= 18L
Milk = 45-18 = 27L
Ratio of Milk : Water is 3:2
Ratio to be changed is 5:3
So the quantity of water is same since we are adding only milk
If ratio is 5:3, the 3x is same and equal to 18L
x=18/3 = 6L
5x = 6*5 =30L
Quantity of milk to be added = 30-27 = 3L
