Question

The strength of a school is 575 and the number of boys is 225 and remaining are girls. Find the ratio of

(a) Number of boys to Number of girls (b) Total Students to Number of boys

• A. (a) 14 : 8 (b) 23 : 9
• B. (a) 9 : 14 (b) 23 : 9
• C. (a) 14 : 9 (b) 9 :23
• D. (a)25 : 4 (b) 23 : 5

Answer 1

The correct option is B

(a) 9 : 14 (b) 23 : 9

Given that the strength of the class = 575

Number of boys = 225

Hence Number of girls = 575 - 225 = 350

(a) Ratio of Number of boys to Number of Girls

Number of boys = 225 and Number of girls = 350

Hence Ratio of Number of boys to Number of girls = $\frac{225}{350}$

= $\frac{9}{14}$

Ratio of boys to girls = 9 : 14

(b) Total Students to Number of boys

Total Students = 575 and Number of boys = 225

Hence of Ratio of Number of Students to Number of boys = $\frac{575}{225}$

= $\frac{23}{9}$

Hence Ratio of total students to Number of boys = 23 : 9
