What is the ratio of the number of boys to the number of girls speaking both the languages?
-
- 23 : 25
- 12 : 25
- 12 : 13
- 25 : 13
- None of these
Correct Option: C
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
Number of boys speaking both the languages = 108
Number of girls speaking both the languages = 117
| Ratio = | Number of boys speaking both the languages |
| Number of girls speaking both the languages |
| = | 108 | = | 12 |
| 117 | 13 |
