Answer: 50 children
18 women
22 men
Explanation:
There were 90 people at a party. The persons consists of men, women and children. The men and women are adults.
Let m = number of men at the party
Let w = number of women at the party
Let c = number of children at the party
There were four more men than women. It means
w = m - 4
There were 10 more children than adults. It means
m + w + 10 = c
c = m + w + 10
Substituting w = m- 4 into the above equation, it becomes
c = m + m- 4 + 10 = 2m+ 6
Note: adults = sum of men and women
There were 90 people at a party. It means
m + w + c = 90
Substituting c = 2m+6 and w = m-4, it becomes
m + m-4 + 2m+6 = 90
4m = 90 - 18 = 88
m = 88/4= 22
w = m- 4 = 22-4
w = 18
c = 2m + 6 = 44 + 6 = 50
c = 50
