Hey there, thanks for the question.

Q.Mary is going to give away all the pencils in her bag. She can give an equal number  of pencils to 4, 3 or 2 people.Which number of pencils could be in her bag?  

a) 28 b) 30 c) 20 d) 32

A. For finding this answer, we need find which given answer has 4, 3 and 2 atleast ONCE as a factor.

For a) 28, it has 4 (2 and 2) , 3 and 2 as factors. So it could be a correct answer.

For b) 30, it has 3 and 2 only as its factors. So it isn't a correct answer.

For c) 20, it has 2 and 4 (2 and 2) only as its factors. So it isn't a correct answer.

For d) 32, it has 2 and 4 (2 and 2) only as its factors. So it isn't a correct answer.

So from all the above given answers, only a) 28 proves to be correct.

Therefore a) 28 is the correct answer.

Thanks and have a great day!
