There are 25% more silver stickers than purple stickers in a bag. After Asher removed 40% of the silver stickers and increased the number of purple stickers by 10%, there are now 112 fewer silver stickers than purple stickers. Find the number of purple stickers at first.

	Silver	Purple
Before	5 u	4 u
Change	- 2 u	+ 0.4 u
After	3 u	4.4 u

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

125% = ¹²⁵₁₀₀ = ⁵₄

Number of silver stickers that Asher removed
= 40% x 5 u
= ⁴⁰₁₀₀ x 5 u 
= 2 u

Number of purple stickers that Asher increased 
= 10% x 4 u
= ¹⁰₁₀₀  x 4 u
= 0.4 u

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

Number of purple stickers in the end
= 4 u + 0.4 u
= 4.4 u

Number of fewer silver stickers than purple stickers in the end
= 4.4 u - 3 u 
= 1.4 u 

1.4 u = 112

1 u = 112 ÷ 1.4 = 80

Number of purple stickers at first
= 4 u
= 4 x 80
= 320

Answer(s): 320
