We have, Water + Milk = Mixture
Original ⇒ 24 + 40 = 64 litres
According to the question
24 + ? = 40

A 64 litre mixture contains water and milk in the ratio 3 : 5. How mu...
To solve this problem, we can set up a proportion using the given ratio and the amount of mixture. Let's denote the amount of water to be added as 'x'.
Given:
Initial ratio of water to milk = 3:5
Total mixture volume = 64 liters
We can set up the proportion as follows:
(3/8) = x/(x+64)
The left side of the proportion represents the ratio of water to the total mixture volume after adding 'x' liters of water, and the right side represents the ratio of water to the total mixture volume before adding any water.
To solve for 'x', we can cross-multiply and then solve for 'x':
3(x + 64) = 8x
3x + 192 = 8x
192 = 8x - 3x
192 = 5x
x = 192/5
x ≈ 38.4
Therefore, approximately 38.4 liters of water must be added to the mixture to achieve a 1:1 ratio of water to milk.
Since we need to provide the answer in whole liters, we can round up the value of 'x' to the nearest whole number, which is 39 liters. However, this is not one of the given options.
To find the closest answer option, we can compare the value of 'x' to each option:
a) 12 liters: 12 < 39="" (not="" the="" />
b) 20 liters: 20 < 39="" (not="" the="" />
c) 24 liters: 24 < 39="" (not="" the="" />
d) 16 liters: 16 < 39="" (not="" the="" />
Since none of the options are greater than 39 liters, we can conclude that the closest answer option is not provided. However, if we round down the value of 'x' to the nearest whole number, we get 38 liters, which is closest to option 'd' (16 liters).
Therefore, the correct answer is option 'D' (16 liters).

Therefore, the correct answer is option 'D' (16 liters).
