There are 25% more grey stickers than white stickers in a bag. After Paul removed 40% of the grey stickers and increased the number of white stickers by 30%, there are now 44 fewer grey stickers than white stickers. Find the number of white stickers at first.

	Grey	White
Before	5 u	4 u
Change	- 2 u	+ 1.2 u
After	3 u	5.2 u

Number of grey stickers in percentage
= 100% + 25%
= 125%

125% = ¹²⁵₁₀₀ = ⁵₄

Number of grey stickers that Paul removed
= 40% x 5 u
= ⁴⁰₁₀₀ x 5 u 
= 2 u

Number of white stickers that Paul increased 
= 30% x 4 u
= ³⁰₁₀₀  x 4 u
= 1.2 u

Number of grey stickers in the end
= 5 u - 2 u
= 3 u

Number of white stickers in the end
= 4 u + 1.2 u
= 5.2 u

Number of fewer grey stickers than white stickers in the end
= 5.2 u - 3 u 
= 2.2 u 

2.2 u = 44

1 u = 44 ÷ 2.2 = 20

Number of white stickers at first
= 4 u
= 4 x 20
= 80

Answer(s): 80
