Problema Solution
Rita is 5 years old and her brother is 54 years old .So,what is the age of her mother?
Answer provided by our tutors
The question has insufficient information to find the age of the mother.
Surely the age of her mother is more than her brother, i.e. 54 (assuming they are not step brother/sister).
Even If she give birth in 16 to her first child, then her age at the birth of Rita is 16+54-5=75 which is absurd.
So, the question is illogical.
