Question

A total of 846 white rulers and violet rulers are in a container. The ratio of white rulers to violet rulers was 1:2. Some pink rulers and yellow rulers were put into the container. For every 4 violet rulers that were already in the container, 14 yellow ones were added. Then the final number of white rulers and pink rulers was 1/2 the final number of violet rulers and yellow rulers. Find the total number of pink and yellow rulers.

Answer 1

white: 846 * 1/3 = 282
violet: 846 * 2/3 = 564
564 / 4 * 14 = 1974
1/2(1974 + 564) - 282 = 987
987 + 1974 = 2961 (Be careful)
