Another YouTube channel F has the subscribers equal to the average of number of subscribers of all the given 5 YouTube channels. If 36% of subscribers of channel F are males then find the difference between the number of male subscribers and the number of female subscribers of channel F. 
» Explain it
C
Total subscribers of channel F

120 + 142 + 98 + 85 + 116  =  561  = 112.2 thousand
5 5

Total male subscribers of channel F = 36% of 112200 = 40392

Total female subscribers of channel F = (112200 – 40392) = 71808

Required difference = (71808 – 40392) = 31416

Hence, option C is correct.
2
It is found that the total number of subscribers of channel B and channel E in the month of June was 180 thousand and 160 thousand, respectively. The number of male subscribers of channel B and channel E combined increases by 20% in June as compared to the total number of male subscribers of channel B and channel E combined till 31st May. If the total number of female subscribers of channel B and channel E combined till 31st May was 115 thousand, then find the increase in number of female subscribers of both channels combined in June as compared to the previous month.
» Explain it
C
Total number of subscribers of channel B and channel E together till May = (142 + 116) = 258 thousand
 
Total number of female subscribers of channel B and channel E together till May = 115 thousand
 
Total number of male subscribers of channel B and channel E together till May = (258 – 115) = 143 thousand
 
Total number of male subscribers of channel B and channel E together in June = 120% of 143000 = 171600
 
Total number of female subscribers of channel B and channel E together in June = [(180000 + 160000) – 171600] = 168400
 
Therefore, the total number of female subscribers of channel B and channel E together increased in the month of June = (168400 – 115000) = 53400

Hence, option C is correct.
3
Find the ratio of total views of all videos of channel D and channel E combined to the total views of all videos of channel B and channel C combined.
» Explain it
A
Total views of all videos of channel D = 160 × 27 = 4320 thousands
 
Total views of all videos of channel E = 240 × 25 = 6000 thousands
 
Total views of all videos of channel B = 198 × 63 = 12474 thousands
 
Total views of all videos of channel C = 140 × 48 = 6720 thousands
 
Required ratio = (4320 + 6000) : (12474 + 6720) = 10320 : 19194 = 1720 : 3199
 
Hence, option A is correct.
4
The ratio of the number of male subscribers to the number of female subscribers of channel D and channel E are 27 : 23 and 61 : 64, respectively. If 26% and 25% of male subscribers of channel D and channel E, respectively are below 20 years of age, then find the total number of male subscribers of channel D and channel E combined who are below 20 years of age.
» Explain it
A
Total number of male subscribers of channel D

85000  × 27 = 45900
50

Total male subscribers of channel D who are below 20 years = 26% of 45900 = 11934

Total number of male subscribers of channel E
116000  × 61 = 56608
125

Total male subscribers of channel E who are below 20 years = 25% of 56608 = 14152

Therefore, total numbers of male subscribers of channel D and channel E combined who are below 20 years of age = (11934 + 14152) = 26086

Hence, option A is correct.
5
The amount paid by YouTube per 1000 subscribers is Rs. 42 and per 10000 views is Rs. 85. Find the difference between the amount of money earned by channel A and channel B till 31st May. 
» Explain it
C
The total amount of money earned by channel A through subscribers

120000  × 42 = Rs. 5040
1000

The total amount of money earned by channel A through views
210000  × 85 × 42 = Rs. 74970
10000

The total amount of money earned by channel A = Rs. (5040 + 74970) = Rs. 80010

The total amount of money earned by channel B through subscribers
142000  × 42 = Rs. 5964
1000

The total amount of money earned by channel B through views
198000  × 85 × 63 = Rs. 106029
10000

The total amount of money earned by channel B = Rs. (5964 + 106029) = Rs. 111993

Required difference = Rs. (111993 – 80010) = Rs. 31983

Hence, option C is correct.
