simple question for simple answer.
the answer is 29.
now here is the explanation.
the average age of three men is 25 implies the sum of their ages is 75 ( logical deduction using formula ).
if the average age of four men has to be 26 then the sum of their ages should be 26 x 4 which is 104.
now we have all that we need
the age of the other man is 104 - 75 which is 29.
the answer is 29.
