Question

The graph below shows the ages of presidents of a country at the time of inauguration or the start of their tenure.

Find the correct option(s) among the following.

• A. The total number of presidents is 45.
• B. The youngest president was 44 years old
• C. The youngest president was 39 years old.
• D. The oldest president is 74 years old.

Answer 1

The correct option is B

The youngest president was 44 years old

On summing up all the frequencies, we get $4+11+14+9+4+2=44$.

Hence, the total number of presidents is 44 and option (A) is incorrect.

The graph starts from 39 but the corresponding frequency is 0. Hence, the age of 44 is the youngest age of president.

Thus, (B) is correct and (C) is incorrect.

The last point on the graph having non-zero frequency is 69. 74 has zero frequency and hence option (D) is incorrect.
