in original jar:

number of reds = 3x

number of yellows = 4x

after the eating:

number of reds = 3x-3

number of yellows = 4x - 6

(3x-3)/(4x-6) = 4/5

16x - 24 = 15x - 15

x = 9

in original:

reds = 3(9) = 27

yellows = 4(9) = 36

**total in jar = 63**

check: 27 : 36 = 3 : 4

after eating: 24 : 30 = 4 : 5
