The following Pie chart represent the percentage - wise distribution of 300 students of class X in a school in six different section A. B. C. D. E. and F.
The table given below the number of boys of class X in six different section A. B. C. D. E. and F.
| Section | A | B | C | D | E | F |
| No. of boys | 36 | 26 | 34 | 28 | x | 20 |
If in section E the ratio of the number of boys to the number of girls is 3 : 4 , then the ratio of number of boys in section E to the number of girls in section C is :
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 18 : 23
Total number of students in section E = (14/100) × 300
⇒ 42
Number of boys in section E = (3/7) × 42
⇒ 18
Total number of students in section C = (19/100) × 300
⇒ 57
Number of girls in section C = 57 - 34
⇒ 23
The ratio of number of boys in section E to the number of girls in section C
⇒ 18 : 23
