SSC CGL 2025 PYQ — Question 82

The correct answer is option 1 i.e. 6 L.

Total mixture = 30 L

Ratio of milk : water = 3 : 2

So, Milk = ${3 \over 5}$ × 30 = 18 L

Water = ${2 \over 5}$ × 30 = 12 L

To make ratio 1 : 1, water must equal milk (18 L).

Current water = 12 L

Water to be added = 18 − 12 = 6 L

Thus, 6 litres of water must be added.
