Question

The graph below shows the ages of presidents of a country at the time of inauguration or 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, youngest president was 44 years old 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.
