Question

There are 2000 students in a school. On January 2^nd, all the students were present in the school except for 4% of the boys. On January 3^rd, all the students are present in the school except for 9.33% of the girls but on both days, the number of students present in the school was the same. The number of girls in the school is?

• A. 400
• B. 1200
• C. 800
• D. 600
• E. None of these

Answer 1

The correct option is D 600

Let Number of girls = x, Then, number of boys - x
$\frac{96}{100}\times (2000-x)+x=(2000-x)+\frac{90.67}{100}\times x$
Solving, we get x = 600
