There are 25% more white beads than pink beads in a bag. After Flynn removed 20% of the white beads and increased the number of pink beads by 10%, there are now 48 fewer white beads than pink beads. Find the number of pink beads at first.

	White	Pink
Before	5 u	4 u
Change	- 1 u	+ 0.4 u
After	4 u	4.4 u

Number of white beads in percentage
= 100% + 25%
= 125%

125% = ¹²⁵₁₀₀ = ⁵₄

Number of white beads that Flynn removed
= 20% x 5 u
= ²⁰₁₀₀ x 5 u 
= 1 u

Number of pink beads that Flynn increased 
= 10% x 4 u
= ¹⁰₁₀₀  x 4 u
= 0.4 u

Number of white beads in the end
= 5 u - 1 u
= 4 u

Number of pink beads in the end
= 4 u + 0.4 u
= 4.4 u

Number of fewer white beads than pink beads in the end
= 4.4 u - 4 u 
= 0.4 u 

0.4 u = 48

1 u = 48 ÷ 0.4 = 120

Number of pink beads at first
= 4 u
= 4 x 120
= 480

Answer(s): 480
