A mother is 21 years older than the child. 6 yearsfrom now themother will be 5 times as old as the child.Question : Where's the father?
highlight to see:
Solution:The mother is 21 years older than the child.M = C + 21In 6 years from now the mum will be 5 times as oldas the child.M + 6 = (C + 6) x 5Hence,C + 21 + 6 = (C + 6) x 5C + 27 = 5C + 30-3 = 4CC = -3/4The child is -3/4 years old, that is, it'll be born in 9months.Thus.. by mathematical induction.......Right now the Father is on top of Mother ( or rahter inside =X)hahaha is ur maths gd?
dont kill cephee (:
