Problema Solution
Of the beads in a box, 3/4 are yellow. Of the remainder, 25% are blue beads and the rest are red beads. There are 15 more red beads than blue beads in the box. How many yellow beads are there?
Answer provided by our tutors
Let 'x' represent the total number of beads.
(3/4)x are yellow
25% of (1/4)x or 0.25(1/4)x = 0.0625x are blue
x - ((3/4)x + 0.0625x) = 15 + 0.0625x

x = 120 beads
(3/4)*120 = 90 yellow beads
There are 90 yellow beads.
