Consider the given question and decide which of the following statements is sufficient to answer the question.
How many cows in a herd are black?
Statements:
1. There are in total 60 cows.
2. 40% of them are black.
a. Total number of cows = 60
b. 40 percent cows are black
The statements above alone cannot identify the number of cows which are black. So using both the statements together we get,
= 0.4$$\times$$60 = 24
Both statements taken together are sufficient to answer the question, but neither statement alone is sufficient.
So option A is correct.
