If the viewership of National for the first half of February is half that of the second half of February, then what is the ratio of viewership of National for the second half of February to that of Aajtak for the whole month?
8:9
National’s share in second half of February = 2/3 x 60 degree = 40 degree
Aajtak’s share in February = 450
The required ratio is 8:9.
Hence (d).
