The annual money spent by a company on search engine marketing, content marketing and affiliate marketing is to be shown on a circlular graph. If the size of each sector of the graph is proportional to the amount of money it represents, did the company spend the most money on search engine marketing?
(1) The angle of the sector that represents content marketing is \(80^{\circ}\)
(2) The angle of the sector that represents affiliate marketing is \(210^{\circ}\)
Total degrees available in a circular graph \(= 360^{\circ}\)
The one that occupies the most degrees will have the most expense.
(1) The angle of the sector that represents content marketing is \(80^{\circ}\)We could have \(80, 70, 210\) for CM, (M&A)M, and SEM respectively and ans YES to the stem.
We could have \(80, 210, 70\) for CM, (M&A)M, and SEM respectively and ans NO to the stem.
INSUFF.(2) The angle of the sector that represents affiliate marketing is \(210^{\circ}\)AM \(= 210^{\circ}\) , We cannot have anything occupy more than \(210^{\circ}\) as max degrees left are \(360-210=150\).
Hence we can ans NO to the stem.

Hope it's clear.
