The wrong term is, 210
Directions (6-10):
6) Answer: c)
In the year 2014, the ratio of boys to girls in School A = 2.6 = 26/10 = 13/5
The total number of boys in School A is 78
= > 13’s = 78
= > 1’s = 6
Total girls in School A = 5’s = 30
In the year 2013, the ratio of boys to girls in School B = 3.6 = 36/10 = 18/5
The total number of girls in School B = 80
= > 5’s = 80
= > 1’s = 16
Total number of boys in School B = 18*16 = 288
Required difference = 288 – 30 = 258
7) Answer: b)
The ratio of boys to that of girls passed in School A in 2015 = 1.4
= > 14/10 = 7/5
Required % = (7/5)*100 = 140 %
8) Answer: a)
Let the number of girls passed from School A in the year 2016 and the number of girls passed from School B in the year 2017 be x,
The ratio of boys to girls in School A in 2016,
= > (BA/GA) = 2.2
= > BA = 2.2x
The ratio of boys to girls in School B in 2017,
= > (BB/GB) = 2.8
= > BB = 2.8x
Required % = [(2.8x – 2.2x)/2.8x]*100 = (0.6/2.8)*100
= 21.42 % = 21 % less
9) Answer: b)
The ratio of number of boys to that of girls in School A in 2012
= > 1.8 = 18/10 = 9/5
The number of boys passed from School A in the year 2012 = 108
= > 9’s = 108
= > 1’s = 12
The number of girls passed from School A in the year 2012 is,
= > 5’s = 5*12 = 60
The ratio of number of boys to that of girls in School B in 2013
= > 3.6 = 36/10 = 18/5
The number of boys passed from School B in the year 2013 = 108
= > 18’s = 108
= > 1’s = 6
The number of girls passed from School B in the year 2013 is,
= > 5’s = 30
Required ratio = 60: 90 = 2: 3
10) Answer: d)
We can’t determine the highest number of girls passed in School A. Here only the ratio of boys to girls passed in School A is given. So, we can’t find the answer.
