There are 25% more green stickers than gold stickers in a bag. After Ryan removed 40% of the green stickers and increased the number of gold stickers by 10%, there are now 126 fewer green stickers than gold stickers. Find the number of gold stickers at first.

	Green	Gold
Before	5 u	4 u
Change	- 2 u	+ 0.4 u
After	3 u	4.4 u

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

125% = ¹²⁵₁₀₀ = ⁵₄

Number of green stickers that Ryan removed
= 40% x 5 u
= ⁴⁰₁₀₀ x 5 u 
= 2 u

Number of gold stickers that Ryan increased 
= 10% x 4 u
= ¹⁰₁₀₀  x 4 u
= 0.4 u

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

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

Number of fewer green stickers than gold stickers in the end
= 4.4 u - 3 u 
= 1.4 u 

1.4 u = 126

1 u = 126 ÷ 1.4 = 90

Number of gold stickers at first
= 4 u
= 4 x 90
= 360

Answer(s): 360
