We are given land area of a country and then in the last column we are given how much % of total land in earth that land is.

Pick up any country and equate. It would be better to choose some % closer to a factor of 100 incase you are calculating manually.

So, India has 2,973,000 and it is nearly 2% of total land area.
Thus, 100% of total land area will be \(2973000*\frac{100}{2}=2973000*50=148650000=1.49*10^8=149*10^6\) or 149 million.

Hope it helps

­The total area of the Land is estimated to be approximately 149 million (sq. km) => Inferred

Try Russia: 17.1 sq. km accounts for 11.48% of total Land area => Total: 149 sq. km

China, the third largest country by land area, is the largest country by population. => Cannot be inferred

No information regrading population is mentioned

Russia is the largest country in the world by land area, with a land area that is more than twice the size of the fifth largest country. => Inferred

Sort by any of the the three categories regarding land area or percentage of land area

=> The fifth largest is Brazil (5.65% of Total land area)
=> Russia takes 11.48% of Total land area 
\(\frac{11.48}{5.65} = 2.03 > 2\)
