A mother is 21 years older than the child.
6 years from now the mother will be 5 times as old as the child.

Solution:
The mother is 21 years older than the child. Let the mother be M and the Child be C
M = C + 21
In 6 years from now the mum will be 5 times as old as the child.
M + 6 = (C + 6) x 5

Hence,
C + 21 + 6 = (C + 6) x 5
C + 27 = 5C + 30
-3 = 4C
C = -3/4


The child is -3/4 years old, that is, it'll be born in 9 months.



Thus.. by mathematical deduction....
Right now, the father is on top of the mother... hahahahahaha!!! Got You?

Kama kawaida, wasiojua hesabu watabisha na wengine watabaki wametoa mimacho.

Good Day my fellow mathematicians!

what does it mean? on top mean older or what

by the way no negative age

wewe unajifunza hesabu?ulitakiwa uanze na 'kitendawili/ tuseme tega au fumbo mfumbue mjinga......but thts not maths kabisa,tukirudi shule labda,au ndo maths za miaka hii?

This is not mathematics !! Kama ungetaka iwe katika mathematics, usingeishia kusema tu that the child WILL be born in 9 months, bali ungehusisha na expressions/equations za probability zinazoonyesha uwezekano wa mama kupewa ujauzito katika mwezi wa mwanzo kuhesabiwa. Wakati mwingine mimba huwa haipatikani kwa sababu ya matatizo ya mama, baba au wote wawili. Zote hizo zinahitaji factors za probability. Mathematics is not such simple.

Hesabu yako inanitatiza kidogo, ninaona kuna kitu cha muhimu ulikiacha katika kujaribu kutengeneza swali. Maelezo kuwa "Miaka sita kutoka sasa, mama atakuwa mara tano zaidi ya umri wa mtoto" haifafanui umri upi wa mtoto unaokuwa refered to. Je umri wa mtoto miaka sita ijayo au umri wa mtoto wa sasa. Kama ni wa sasa, na kwa mujibu wa solution yako ya -3/4yrs becomes invalid. Kwa kifupi kama wengi walivyosema, haijakaa kihesabu zaidi ya ki-joki. Nafikiri ni kuwajoki unaofikiri hawajui hesabu, labda.
