Step-by-step explanation:      Given:  -     In an examination hall 144 people were present. of these 1/2 were boys and of them 4/9 were girls. The rest were teachers.     To   find:  -      How many students were there in the hall?     Solution  :  -     Given that    Total number of people were present in the examination hall = 144    Number of boys = 1/2 of the total people    => (1/2)×144    => 144/2    => 72    Total number of boys = 72    Total number of girls = 4/9 of the total people    => (4/9)×144    => (4×144)/9    => 4×16    => 64    Number of girls = 64     Total number of boys and girls = 72+64 = 136     Total number of teachers    => 144-136    =>8    Number of teachers = 8    (or)    Total people present in the examination hall    => boys+girls+teachers    => (144/2)+(4×144/9)+ Teachers = 144    => Teachers = 144 - (144/2)-(4×144/9)    => Teachers = 144 -72-64    => Teachers = 144 - 136    Number of teachers = 8       Answer  :  -     Total number of students were present in the examination hall =  1  3  6
