1
What is the ratio of the number of male followers who follow Baba2 to the number of female followers who follow Baba1?
» Explain it
A
Following the common explanation, we get

The number of male followers who follow Baba2 = 140 + 126 + 140 + 70 = 476

The number of female followers who follow Baba1 = 90 + 100 + 40 + 100 = 330

∴   Reqd ratio =  476  =  238  = 238 : 165
330 165
Hence, option A is correct.

Common Explanation:

Total number of followers = 1200

And the given ratio of Male to Female = 7 : 5, Therefore, man will be 700 and female will be 500.
 
Baba Male Followers (700) Female Followers (500)
Only Baba1 10% of 700 = 70 18% of 500 = 90
Only Baba 2 20% of 700 = 140 10% of 500 = 50
Only Baba 3 12% of 700 = 84 12% of 500 = 60
Only Baba1 and Baba3 10% of 700 = 70 20% of 500 = 100
Only Baba3 and Baba2 18% of 700 = 126 12% of 500 = 60
Only Baba1 and Baba2 20% of 700 = 140 8% of 500 = 40
All the Babas 700 – (70+140+84+126+70+140) = 70 500 – (90+50+60+100+60+40) = 100
2
The total number of male followers following less than two Babas is what percent of the total number of female followers following more than one Baba?
» Explain it
C
Following the common explanation, we get

The number of male followers who follow less than two Babas = 70 + 140 + 84 = 294

Total number female followers who follow more than one Baba = 60 + 100 + 40 + 100 = 300

∴   Reqd% =  294  × 100 = 98%
300

Hence, option C is correct.
