Question

In a basket, there are beads of 3 different colours, yellow, red and white. There are 220 more red than white beads. There are 1/3 as many yellow beads as white beads. The number of white beads is 24% of the total number of beads in the basket. How many red beads are there in the basket?

Answer 1

number of white --- x
number of red ---- x+220
number of yellow ---- (1/3)x

total = x + x+220 + x/3
= 7/3 x + 220

number of white beads is 24% of the total number of beads
----> x = .24(7/3 x + 220)
x = .56x + 52.8
.44x = 52.8
x = 120 beads
