a box of red,blue and green pencils contains 20 in all.there are 6 times as many blue pencilas green ones,and fewer rd pencils than blue ones. how many red pencilsare in he box

3 answers

let x be the number of green ones
blue one = 6x
There are 7 or 14 blue and green pencils. Blue ones, respectively, 6 or 12, and green ones 1 or 2.

In all there are 20 pencils, hence, there are two possibilities for the reds:
either there are 20−7=13,
or 20−14=6.

But the reds are less than the blue ones, so the only possible answer is 12 blue pencils, 2 green pencils and 6 red pencils.
