Question

A college with 7154 students had a teacher for every 146 students last year. This year, 111 students joined the college and 1073 students left. Similarly, 14 teachers left the college, and 8 teachers joined. What is the new ratio of the teacher to students (number of students per teacher)?
 A.150 B.135 C.139 D.144

Answer 1

Number of students this year   =   7154 + 111 - 1073
                                                 =   6192
Number of teachers in previous year   =  7154 /146
                                                             = 49
Number of teachers this year   =   49 + 8 - 14
                                                 =    43
New ratio of teachers to students  =  6192 :  43
                                                       =  6192 / 43
                                                       =   144

Hence, the answer will be 144 (option D).
