Question 47

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.

Solution

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.
