1/6 are red and 1/3 are blue
that means 1/6 + 2/6 = 3/6 = 1/2 are either red are blue
3/7 of the remainder is 3/14 of the total
3/14 x = 27
x = 27(14/3) = 126
there are 126 caps
126 / 6 = 21 are red
126 / 3 = 42 are blue
there are 63 left, of which 3/7 are green
3/7 (63) = 27 ==> 27 green caps
total of 126 caps
Hope this helps :)
