**anon**, Friday, December 17, 2010 at 10:34pmIn jar 1, 1/8 of the marbles are white.

In jar 2, 1/10 of the marbles are white.

Since the jars are filled with an equal amount of marbles, take this value to be x. Therefore, x/8 + x/10 should equal to 90, the total number of white marbles.

From this, we get x = 400 marbles altogether.

This means 200 marbles in each jar.

In jar 2, 9/10 of the marbles are red. There are 200 marbles in this jar. (9/10)*200 = 180 red marbles in jar 2.

Sorry for the late response.
