A mother is 21 years older than her son. Six years from now the mother will have an age 5 times that of the child.
Question: Where is the father now? Yes, you did not read wrong … where is the Father?
Some calculations have to be done to get the answer!
Incredible as it may seem the answer is given by mathematics!
See the answer below… it’s very interesting:
The mother is now Y years old
The boy is now X years old
So with the mother 21 years older: Y = X + 21
6 years from now: (Y + 6) and (X + 6)
So with the mother 5 times older than her son: Y + 6 = 5 (X + 6)
Y + 6 = 5 X + 30
Y = 5X + 24
Then, replacing in the first equation = X + 21 we have:
5X + 24 = X + 21
-4X = 3
X = -¾
The boy is now -¾ years old, that is, – 9 months (minus nine months !!!).
The answer is logical:
If the boy is exactly nine months old, he will be born in nine months,
Answer to the proposed problem:
- The father is now “eating” the mother, while you break your head !!!
