A is as much younger than B as he is older than C. If the sum of the ages of B and C is 40 years, what is definitely the difference between B and A’s age?
A is as much younger than B as he is older than C.
So, the age of A < the age of B
And the age of A > the age of C
The summation of the age of B and C = 40 years
From the above data, we cannot determine the difference in age between B and A.
