Question 1089235
.
OK.

All calculations by the other tutor are correct.


So, &nbsp;the answer &nbsp;<U>12 years</U>&nbsp; is mathematically and formally correct.

Thus the child is &nbsp;<U>12</U> &nbsp;years old.


But then the problem formulation loses its sense, &nbsp;because the child, &nbsp;the 6-th member of the family, &nbsp;just was present three years ago.



What is the conclusion from this story  &nbsp;&nbsp;? &nbsp; &nbsp;??  &nbsp; &nbsp;???


The conclusion is that the problem is &nbsp;&nbsp;<U>EITHER</U> &nbsp;a) &nbsp;self-contradictory, &nbsp;&nbsp;<U>OR</U> &nbsp;b) &nbsp;nonsense, &nbsp;&nbsp;<U>OR</U> &nbsp;&nbsp;c) &nbsp;is incorrectly formulated.
