Read the passage below and solve the questions based on it.
Go through the following definitions
A + B = All A are B
A * B = Some A are B
A @ B = No A are B
A # B = Only A are B
Following table gives the average age break-up of all the students at IIM-A (2005 batch):
Assume that all the students mentioned above are either males or females. The minimum entry age in the IIM is 20 years (at the time of taking the entrance exam to qualify for IIM-A). No fresher can be a working professional and males/females/engineers can be either a fresher or a working professional. Everybody is either a fresher or a working professional.
Following statement is definitely true: M + E. What is the average age (in years) of all the engineers who are not male?
