Question

There are 73 red, blue and green marbles in a jar. There are twice as many red marbles as blue marbles. There are 19 more marbles than green marbles. How many green marbles are there?

Answer 1

We know,

Blue marbles = 19 + Green Marbles

Then,

Let green marbles be 1 and 20 blue.

There must be 40 red marbles as red = 2*blue

Total only becomes = 61

For every 1 green marble = 2 red + 1 blue

So,

Just add 3 green marbles,

Finally = 4 G + 23 B + 46 R

Answer 2

Answer:

Explanation:

Blue marbles x

Red marbles 2x

Green marbles x+19

X+2x+x+19= 73

4x=73-19= 54

4x = 54 = 13.5

Blue marbles = 13.5

Red marbles 13.5 ×2 = 27

Green marbles 27 +19= 46
