What is the approximate ratio of the areas of state B to the areas of state A and G together.

Options

A. `1:3.8`
B. `1:3.5`
C. `1:5.2`
D. `1:4.1`

Explanation

Following table can be made easily:
Total area =37249 sq kilometres
` {:("State","Density of population (in thousands)","Approx % area"),(A,(112200)/(6230)=18("approx"),16.7),(B,(83800)/(2540)=33("approx"),6.8),(C,(64900)/(8135)=8("approx"),21.8),(D,(572)/(7436)=(1)/(13)xx100=7.69("approx"),20),(E,(71100)/(4893)=14.5("approx"),13),(F,(286)/(3718)=(1)/(13)xx100=7.69("approx"),10),(G,(86000)/(4297)=20("approx"),11.5):}`
Note : Density of population is the population per square kilometre.]
Required answer `=2540:(6230+4297=)=(2540)/(10527)=(1)/(4.1)`
