Answer:
total number of students in school B= 380
Let dinner = x
380=110+160+x
380=270+x
380-270=x
110=x
therefore, number of students in B school who have dinner as there favourite meal = 110
total number of students in school B = 240
As dinner in both school A is equal to school B
dinner= 110
Let lunch =y
240=60+110+y
240=170+y
240-170=y
70=y
therefore, number of students in school A who have lunch as there favourite meal =70
