Out of 162 students in a school, 72 are boys and the remaining are girls. What is the ratio of the number of girls to the number of boys in that school?

Correct option is B

Given:

Total number of students = 162

Number of boys = 72

Solution:

Number of girls = 162 - 72 = 90

Ratio of number of girls to boys = $$\frac{90}{72} =\frac{5}{4}= 5:4$$​​

Hence option(b) is correct
