The number of students in each section of a school is 24. After admitting new students, three new sections were started. Now, the total number of sections is 16 and there are 21 students in each section. The number of new students admitted is :


A) 14

B) 24

C) 48

D) 114

Answer:

Option B

Explanation:

Number of students per section before joining = 24
Number Of sections before joining = 13
Then total number of students before joining = 24 x 13 = 312
Number Of sections added after joining = 13 + 3 = 16
Number Of students per section after joining = 21
Then total no. Of students after joining = 16 x 21 = 336
So, total no. Of students joined = 336 - 312 = 24
