Solutions

It is clear that the two least popular channels among the five are NDTV and India Tv.
⇒ Number of viewers of India Tv during elections = 20,00,000 + 2,00,000 = 22,00,000
⇒ Number of viewers of NDTV during elections = 30,00,000 – 1,50,000 = 28,50,000
Total number of viewers of NDTV and India tv during elections = 22,00,000 + 28,50,000 = 50,50,000
Total number of viewers of NDTV and India tv during non-elections = 20,00,000 + 30,00,000 = 50,00,000
The difference between the viewers of the two least popular channels during the election and the non-election periods = 50,50,000 – 50,00,000
∴ The difference = 50,000

Solutions

Total number of Aajtak viewers increased during election = 10% of 90,00,000 = 9,00,000
⇒ Number of viewers during elections are = 90,00,000 + 9,00,000 = 99,00,000
Total viewers of both the channels during non-election = 90,00,000 + 80,00,000 = 170,00,000
Total viewers of both the channels during elections = 99,00,000 + 89,60,000 = 188,60,000
∴ The ratio of viewers of AajTak and ABP during elections to during non-elections = 188,60,000 ÷ 170,00,000 = 943 ∶ 850

Solutions

Total number of NDTV viewers decreased during election = 5% of 30,00,000 = 1,50,000
⇒ Number of viewers during elections are = 30,00,000 – 1,50,000 = 28,50,000
Total number of India TV viewers increased during election = 10% of 20,00,000 = 2,00,000
⇒ Number of viewers during elections are = 20,00,000 + 2,00,000 = 22,00,000
Total number of Zee news viewers increased during election = 5% of 50,00,000 = 2,50,000
⇒ Number of viewers during elections are = 50,00,000 + 2,50,000 = 52,50,000
∴ The average number of viewers of these channels during the election period = (28,50,000 + 22,00,000 + 52,50,000) ÷ 3 = 34,33,333

Solutions

Viewers of ABP during non-election period = 80,00,000
Number of viewers increased during election period = 12% of 80,00,000 = 9,60,000
⇒ Total number of viewers of ABP during election period = 80,00,000 + 9,60,000 = 89,60,000
Total number of viewers of all channels during non-election period = 270,00,000
The percentage of total viewers of ABP during election period to the total viewers of all channels during non-election period = (89,60,000/270,00,000) × 100
∴ The percentage of total viewers = 33.18%
