In a class of 96, boys = girls. Ritu is 20th from top, and 13 boys are ahead. How many girls are behind her?
Show answer & explanation
Correct answer: C
Explanation
Given:
• Total number of students = 96
• Number of boys = Number of girls = 96 / 2 = 48
Step-by-step deduction:
• Ritu is 20th from the top, which means there are 19 students ahead of her.
• Out of these 19 students, 13 are boys.
• Therefore, the number of girls ahead of Ritu = 19 − 13 = 6 girls.
• Including Ritu herself, the number of girls from the top up to Ritu = 6 + 1 = 7 girls.
• The number of girls behind Ritu = Total girls − 7 = 48 − 7 = 41.
Hence, the correct option is (C).
