Let initial quantity of sugar = 4a and milk = 5a
(Initial quantity of sugar)/(Initial quantity of milk + Quantity of milk added) = 2/3
⇒ 4a/(5a + 7) = 2/3
⇒ 10a + 14 = 12a
⇒ 2a = 14
⇒ a = 7 liters
∴ Quantity of Sugar in new mixture is same as initial so = 4a = 4 × 7 = 28 liters

Understanding the problem:
Given:
- Initially, the ratio of sugar to milk in the mixture is 4 : 5.
- When 7 liters of milk is added, the new ratio becomes 2 : 3.

Solution:

Step 1: Solving for the initial quantities of sugar and milk
Let's assume the initial quantities of sugar and milk in the mixture are 4x and 5x respectively.
Therefore, the total initial quantity of the mixture = 4x + 5x = 9x

Step 2: Solving for the final quantities of sugar and milk after adding 7 liters of milk
After adding 7 liters of milk, the new quantity of milk becomes 5x + 7 and the new quantity of sugar remains 4x.
According to the given ratio 2 : 3, we can write the equation as:
4x / (5x + 7) = 2 / 3
Solving this equation, we find x = 7.
Therefore, the initial quantity of sugar = 4 * 7 = 28 liters.

Final Answer:
Hence, the total quantity of sugar in the new mixture is 28 liters, which corresponds to option (b).
