35% of ab = ?venmic wrote:What is 35 percent of ab?
(1) b is 200 percent of a.
(2) 50 percent of b is a.
Simple try
(1) b = 200% of a implies b = 2a
So, 35% of ab = 0.35 * 2a², but we don't know the value of a.
So, (1) is NOT SUFFICIENT.
(2) 50% of b = a implies b/2 = a or b = 2a, which gives the same info as statement 1.
So, again (2) is NOT SUFFICIENT.
Combining (1) and (2), also is NOT SUFFICIENT to answer the question.
The correct answer is E.
