Answer:

The sum of the other three numbers is 96

Explanation:

Assume :

  • First number = a
  • Second number = b
  • Third number = c
  • Fourth number = d

Known :

  • (a + b + c + d)/4 = 30
  • a = 24

Asked :

  • b + c + d = ?

Solution :

(a + b + c + d)/4 = 30

a + b + c + d = 30 x 4

a + b + c + d = 120

Since a = 24,

a + b + c + d = 120

24 + b + c + d = 120

b + c + d = 120 - 24

b + c + d = 96

Conclusion :

The sum of the other three numbers is 96
