Acid : water = 12x : 13x
Total mixture = 100 L
12x + 13x = 100
x = 4
Acid = 12x = 48 L
Water = 13x = 52 L
New mixture = water = 52 + 4 = 56
Ratio of acid to water = 48 : 56 = 6 : 7
Hence the correct option is C.

In a mixture of 100L, the ratio of acid to water is 12 : 13. Another 4...
Initial Mixture:
- Total mixture: 100L
- Ratio of acid to water: 12 : 13

Calculation:
Let the amount of acid be 12x and the amount of water be 13x in the initial mixture.

After adding 4L of water:
- New total mixture: 100L + 4L = 104L
- New amount of water: 13x + 4
- New ratio of acid to water: 12x : 13x + 4

Solving for x:
Given that 12x : 13 = 12x : 13x + 4
Cross multiplying, we get 13(12x) = 12(13x + 4)
156x = 156x + 48
48 = 156x - 156x
48 = 48
x = 1

Calculating new ratio:
- New amount of water: 13(1) + 4 = 17
- New ratio of acid to water: 12(1) : 17 = 12 : 17

Answer:
Therefore, the new ratio of acid to water in the mixture after adding 4L of water is 12 : 17, which simplifies to 6 : 8 or 6 : 7. Hence, the correct answer is option 'C' - 6:7.
