If land and water in ratio of1;2 and northeen hemisphere is 2;3 than tell me sothern hemisphere ratio

**Answer: 4: 11**

**Solution:-**

If the ratio of land and water = 1: 2

Then, the part of the earth = 1/3 and part of water = 2/3

The ratio of earth and water on northern hemisphere = 2: 3

Then, part of earth on norther hemisphere = 2/5 and part of water on northern hemisphere = 3/5

Getting a common denominator

Then, part of earth and water in the word = 10/30 and 20/30

part of earth and water in northern hemisphere = 6/30 and 9/30

Then, part of earth in southern hemisphere = 10/30 – 6/30

= 4/30

And, part of water in southern hemisphere = 20/30 – 9/30

= 11/30

Then, the ratio of earth and water in southern = (4/30)/(11/30)

= 4/11

= 4: 11

Hence, the correct answer is 4: 11.
