Question

Jason has twice as many red marbles as blue marbles. He puts them in two jars in such a way that the ratio of the number of red marbles to blue marbles in jar 1 is 2:7 and there are only red marbles in jar 2. The number of red marbles in jar 2 is how many times the number of red marbles in jar 1?

Answer 1

let ther b 2 red marbls and 7 blue marbles in jar 1
so the ratio would be
RED:BLUE
2:7
and given that he has twice as many Red as Blue marbles, that means he has 14 Red marbles as he has 7 Blue ones.

since Jar 2 contains only Red balls , and we know he has 14 Red out of which 2 are in Jar 1
so Jar 2 will have 12 Red marbles,
so
\[\frac{red marbles In jar 1}{red marbles In jar2}\]\[=\frac{12}{2} = 6\]
