Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 5 : 4.
Number of students passed from institute A = 22% of 1200 = 264.
Number of boys and girls who passed from institute A ,
Boys = 5/11 × 264 = 120
Girls = 6/11 × 264 = 144.
Number of students passed from institute D = 20% of 1200 = 240
Number of boys = 40% of 240 = 96.
Number of girls = 240 - 96 = 144.
The ratio of the number of boys who passed from institute A to that of boys who passed from institute D is,
120 : 96 = 5 : 4.
