Answer 1

Answer:

options C

10 kg

Explanation:

water:milk::1:2

given water +milk =30kg

water is 10 kg and milk is 20 kg

according to question,

water:milk :: 1:1

I.e. water =milk

milk is 20 kg

so water must be 20 kg while 10 kg water is present itself

so,10 kg more water must be added.

and one more thing liquid is measured in liter not in kg
