Question 142

At an institute, 99% of the 100 students are girls but only 98% of the students living on the compus are girls. If same girls live on campus, how many students live off compus ?

Solution

Total students = 100 and Number of girls = 99, Number of boys = 1

Let number of students living off campus = $$x$$, and number of students living on campus = $$(100-x)$$

2% of boys live on campus (since there is only 1 boy)

=> $$\frac{2}{100}\times(100-x)=1$$

=> $$100-x=50$$

=> $$x=50$$

=> Ans - (C)
