Answer 1

Answer:

45

Step-by-step explanation:

to find the real quantities

4:3 will be considered as 4x+3x =105 (let x be the constant)

7x= 105

x=15, so milk is 60 litres and water is 45 litres

now to make it into 2:4 all we need to do is add some extra quantity

105 + y = 2z+4z

105+y = 6z

now from the given options check that what Value can be added to 105 so that it is divisible by 6

i.e 45

by adding 45

105+45 = 6z

150= 6z

z=25

the new quantities are 50 milk: 100 water i.e 2:4
