n = number of passengers
n = 50
m = number of mens
m = ( 3 / 10 ) * 50 = 150 / 10 = 15
r = the rest
r = 50 - 15 = 35
w = number of womans
w = ( 2 / 7 ) * r = 2 * 35 / 7 = 70 / 7 = 10
c = number of childrens
m + w + c = 50
15 + 10 + c = 50
25 + c = 50 Subtract 25 to both sides
25 + c - 25 = 50 - 25
c = 25
c - w = 25 - 10 = 15
THERE WERE 15 MORE CHILDREN THAN WOMAN
