Answer 1

Answer:

He was working as a director of the Post and Telegraph Department in Kolkata city. During his tenure one day, a certain sad soldier from Kerala came to visit him. He was unable to know anything about his father's health. Because at that time, the travel-time of the letter was almost more than a month to reach from Kerala to Arunachal Pradesh. Because of this, the thinking of scholar Mr. Velankar started, ‘How can I reduce the travelling time of letters?’ Uncomprehensive handwriting, different regional languages, incomplete address were many obstacles. Hence, numbers were used by that mathematician. The country was divided into 8 parts by him. He further divided them into regional sub-divisions. Because of that, we get letters without any hassle even now.

Mr. Velankar who was fond of discipline, also liked the subject of music. He was an expert in playing violin and also in playing tabla.
