15 more red beads than blue. of the remaining 25% are blue. 
25%= 1/4
15 divided by the remaining three quarters is 5. which means that each quarter is 5 beads in the remaining 25%.

red beads: 15
blue beads 5    25% of beads is 20.

20 multiplied by the 3 quarters left is 60.

there is a total of 60 yellow beads
