<result>C</result>
the number of students in each section of a school is 24. after admitting new students, 3 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:
subtract(multiply(21, 16), multiply(24, subtract(16, 3)))
original number of sections = 16 - 3 = 13 original number of students = 24 x 13 = 312 present number of students = 21 x 16 = 336 number of new students admitted = 336 - 312 = 24 so the answer is option c ) 24 .
