Let total no. of people = x
No. of adults = x/4
No. of children = 60+(x/4)
= (240+x)/4
By the data,
(240+x)/4 + x/4 = x
(240+2x)/4 = x
240+2x = 4x
4x - 2x = 240
2x = 240
x = 120.
So, total no. of people = x = 120
no. of adults = x/4 = 120/4 = 30

Answer:
Let us suppose total no. of people be x.
No. of adults = x/4
No. of children = x/4 + 60
=> x/4 + x/4 + 60 = x
= 2x/4 - x = -60
= -2x/4 = -60
= x = -60 X 4/-2 = 120
Therefore, no. of adults are 1/4 X 120 which is equal to 30.
