Answer
The age at which the women body fat reaches maximum is $65$ and the percentage is $26$.
Work Step by Step
From the given graph it can be observed that at the age of 25, the percent body fat in men is 23. It then starts increasing until it reaches the value of 26 at the age of 65.
Thus, the interpretation of the graph is that the percent body fat in men increases in the interval $\left( 25,65 \right)$.
The maximum value is obtained at an age of 65 years of age, the percent body fat in men is 26.
Hence, at 65 years of age, the percent body fat in men reaches a maximum value, that is, 26.
