Solution

The correct option is B Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.

(b)

Given that 2G+3B=20

Using statement I that number of girls is not more than 5, we have G=1, B=6 and G=4, B=4. since we cannot get a single solution from this statement it is not sufficient to answer the question

If statement II is used, 3B+2G=20, we have G=4 and B=4

Hence, statement II alone is sufficient to answer the question
