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.
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.
