Question

A group of teachers and pupils attended a concert. The teachers paid $1200 altogether and the pupils paid $640 altogether for their tickets.
The price of an adult ticket was $60 and there were 4 more female teachers than male teachers. How many male teachers were there in the group

Answer 1

If there were x male teachers, then we know that

f = m+4, so
(m + m+4) * 60 = 1200

Now just find m

Answer 2

1200 /60= 20 teachers.
20/2=10.
there were 4 more female teachers so 10 plus 4 =14.
and 10-4=6.
so there were 6 male teachers.

Answer 3

$1200 ÷ $60 ⇒ To find out the number of teachers
= 20 teachers
= 20 ÷ 2 = 10

There were 4 more female teachers. So,

10 + 4 = 14
20 - 14 = 6

Male teachers = 6
Female teachers = 14

Answer 4

1200/60= 20 (adults)
Female (f) + male (m) = 20
F = 20- m

F = 4+m
20-m = 4+m
2m = 16
m = 8
male teachers = 8
