Question

A jar on a shelf has 300 jelly beans three tenths of the jellybeans are blue four tenths are green and the rest are honey colored how many jellybeans are either green or blue

Answer 1

210

Explanation:

A jar on a shelf has 300 jelly beans.

Three-tenths of the jellybeans is blue.

That means the number of blue jelly beans is
`300 * (3)/(10) =90`

Now, four-tenths of the jelly beans are green.

That means the number of green jelly beans is
`300 * (4)/(10) =120`

Therefore, the number of jelly beans which are either green or blue is (120 + 90) = 210. (Answer)
