A school has 400 students- boys and girls, who are in the ratio of 3:5. The students speak Hindi, English or both the Languages. 12% of the boys speak only Hindi, 22% of the girls speak only English, 24% of the total students speak only Hindi and the number of boys speaking both the Languages is six times the number of boys speaking only Hindi.
How many boys speak Hindi?CorrectTotal Number of students = 400
Ratio of boys and girls; B: G = 3: 5
Number of boys = 400 * 3/8 = 150
Number of girls = 400 * 5/8 = 250
Total number of students who speak only Hindi (400) -> 24% of 400 = 96
Number of Boys (150):
Only Hindi ->12% of 150 = 18
Only English -> 150 – 18 – 108 = 24
Both -> 6 * 18 =108
Number of Girls (250):
Only Hindi->96 – 18 = 78
Only English ->22% of 250 = 55
Both->250 – 78 – 55 = 117
Number of boys who speak only Hindi = 18
Number of boys who speak Hindi + English = 108
18 + 108 = 126
Therefore, the numbers of boys who speak Hindi are 126IncorrectTotal Number of students = 400
Ratio of boys and girls; B: G = 3: 5
Number of boys = 400 * 3/8 = 150
Number of girls = 400 * 5/8 = 250
Total number of students who speak only Hindi (400) -> 24% of 400 = 96
Number of Boys (150):
Only Hindi ->12% of 150 = 18
Only English -> 150 – 18 – 108 = 24
Both -> 6 * 18 =108
Number of Girls (250):
Only Hindi->96 – 18 = 78
Only English ->22% of 250 = 55
Both->250 – 78 – 55 = 117
Number of boys who speak only Hindi = 18
Number of boys who speak Hindi + English = 108
18 + 108 = 126
Therefore, the numbers of boys who speak Hindi are 126 - Question 2 of 10
