Question

at the party, 3/8 of the people were children and the rest were adults. given that there were 40 more adults than children, what was the total number of people at the party?

Answer 1

the total no of people are 64

Answer 2

Solution :

let no. of childrens = c

and no. of adults = a

given that

3/8( a + c) = c

also,

a = c + 40

so ,

3/8 ( c + 40 + c) = c

3/8 (2c + 40) = c

3/4 c + 15 = c

c - 3/4 c = 15

1/4 c = 15

c = 60

a = 60 + 40 = 100

a = 100

total members at party = 160

so there were 60 childrens , 40 adults

in total there were 160 members
