Tom has a total of 95 beads. He has 20 more red beads than blue beads. He has twice as many white beads as red beads. How many blue beads does Tom have?

Answer 1

Assuming he has only reds, blues, and whites

blue beads ---- x
red beads ----- x+20
total of blues and reds = 2x + 20
white beads = 95-(2x+20) = 75 - 2x

75-2x = 2(x+20)
75-2x = 2x + 40
-4x = -35
x = 35/4 , which is not a whole number

the question is bogus, do you have a typo?
e.g. a total of 96 beads would have worked.
