Correct Option: B
Given : -
According to question ,
Total number of students in school = 400 students
Ratio of boys and girls in school = 3 : 5
Let us assume the ration is P.
Number of boys = 3P
Number of girls = 5P
3P + 5P = 400
8P = 400
P = 50
Number of boys = 3P = 3 x 50 =150
Number of girls = 5P = 5 x 50 = 250
% of the boys speak only Hindi = 12%
According to question ,
The total number of boys speaking Hindi
= 12% × Number of boys + six times the number of boys speaking only Hindi
⇒18 + 108 = 126
