Verified Answer
Number of students in 4th and 5th class is in the ratio 6 : 11. 40% in...
B) 54.8%
Explanation: Total students in both = 6x+11x = 17x Boys in class 4 = (60/100)*6x = 360x/100 Boys in class 5 = (52/100)*11x = 572x/100 So total boys = 360x/100 + 572x/100 = 932x/100 = 9.32x % of boys = [9.32x/17x] * 100

Number of students in 4th and 5th class is in the ratio 6 : 11. 40% in...
Given data:
Ratio of students in 4th and 5th class = 6 : 11
40% of class 4 students are girls
48% of class 5 students are girls

Let us assume that there are 6x students in class 4 and 11x students in class 5.
Therefore, the total number of students = 6x + 11x = 17x

Number of girls in class 4 = 40% of 6x = 2.4x
Number of boys in class 4 = 6x - 2.4x = 3.6x

Number of girls in class 5 = 48% of 11x = 5.28x
Number of boys in class 5 = 11x - 5.28x = 5.72x

Total number of boys in both classes = 3.6x + 5.72x = 9.32x

Percentage of boys in both classes = (total number of boys / total number of students) x 100
= (9.32x / 17x) x 100
= 54.8%

Therefore, the percentage of students in both classes who are boys is 54.8% (option B).
