Answer 2

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
