India first participated at the Olympic Games in $1900$, with a lone athlete Norman Pritchard winning two medals – both silver – in athletics and became the first Asian nation to win an Olympic medal. The nation first sent a team to the Summer Olympic Games in $1920$ and has participated in every Summer Games since then. India has also competed at several Winter Olympic Games beginning in $1964$. Indian athletes have won $35$ medals, all at the Summer Games.

The number of medals which India won in the last six years in Summer Olympics Games is represented using the bar graph as shown below:

If the total number of medals won by India is $35$, then the percentage of the medals won by India in $2020$ to the total number of medals is

Coronavirus disease (COVID$-19$) is an infectious disease caused by the SARS-CoV$-2$ virus.

Most of the people who got infected with this virus have experienced mild to moderate respiratory illness and recovered soon. But, some people have become seriously ill and required medical attention. Older people who have other medical conditions like diabetes, chronic respiratory disease, or cardiovascular disease etc. will be infected easily and develop serious illness. Anyone, at any age, can get sick with Coronavirus and become seriously ill or die.

During a survey, the ages of patients who are infected and admitted in a city hospital are recorded. The data is represented using the histogram as show below:

The class width of the given data is
