Directions: The questions below consist of a question followed by two statements labelled l and II. You have to decide if these statements are sufficient to answer the question. Give answer
how many legs are there in a group of animals?
I. Statements: I. There are 20 heads.
II. Half of the animals are birds while half are cows.

Options

A. if only statement I is sufficient but statement II is not,
B. If only statement II is sufficient but statement I is not,
C. if both statements I and II are together sufficient to answer the questions although neither statement suffices by itself
D. if the two statement are not sufficient but still more data is needs to answer the question.

Answer

C

Explanation

From the two statements together it is obvious that there are 10 birds and 10 cows. Hence, there are
`10 xx 2+ 10 xx 4 = 60` legs.
