Answer:
4:1
Step-by-step explanation:
Let us assume that the cost of water is free, that is Rs.0.
Let x represent the number of liters of milk, y represent the number of liters of water and z represent the volume of the mixture in liters, hence:
z = x + y (1)
Milk cost Rs.5 per liter, water cost Rs.0 per liter and the mixture cost Rs.4 per liter. Therefore:
5x + 0(y) = 4z (2)
Substituting z = x + y in equation 2 gives:
5x + 0(y) = 4(x + y)
5x = 4x + 4y
5x - 4x = 4y
x = 4y
x / y = 4 / 1
x : y = 4 : 1
The proportion in which the milk is to be mixed with water is 4 : 1, that is 4 liters of milk per 1 liter of water
Answer:22

4 - (2x + 4) = 5
4 - 2x - 4 = 5
-2x = 5
x = - 5/2 <==
Answer:
The single decimal multiplier will be 1.0712
Step-by-step explanation:
Let the number is x.
So, increasing the number by 4% will give the number 
Now, if the number 1.03x is again increased by 3%, then it will become
.
Therefore, the single decimal multiplier that I will use to increase by 4% followed by a 3% increase is 1.0712. (Answer)
