उत्तर

1. The greatest amount of total is spent in Newspapers.

2. The greatest amount of total is spent in Radio.

3. Total = 40 + 42 + 23 + 7 + 11 + 39 + 14 + 15 + 9 = 200

% Spent in direct mail = `39/200 xx 100`

% Spent in direct mail = 19.5

4. Total = 40 + 42 + 23 + 7 + 11 + 39 + 14 + 15 + 9 = 200

Newspaper + Magazine = 42 + 23 = 65

% Spent in Newspaper and Magazine = `65/200 xx 100`

% Spent in Newspaper and Magazine = 32.5

5. The various media types on which not much amount is spent must be included in Miscellaneous.
