Adam has some stickers
He gives away ¹₃ and an additional 50 stickers to Bryan.
He gives away ³₁₀ of the remainder and 14 more stickers to Chris
and ³₇ of the rest to David.
Adam has 4 stickers left.
How many stickers does he have at first?
Number of stickers that Adam gives to Bryan = ¹₃ of the total + 50
Number of stickers that Adam gives to Chris = ³₁₀ of the remainder + 14
Number of stickers that Adam gives to David = ³₇ of the rest
Number of stickers left = 4


Working backwards.
1 - ³₇ = ⁴₇

⁴₇ of the rest → 4
¹₇ of the rest → 4 ÷ 4 = 1
⁷₇ of the rest → 7 x 1 = 7

1 - ³₁₀ = ⁷₁₀

⁷₁₀ of the remainder = 14 + 7 = 21
¹₁₀ of the remainder = 21 ÷ 7 = 3
¹⁰₁₀ of the remainder = 10 x 3 = 30

1 - ¹₃ = ²₃
²₃ of the total = 30 + 50 = 80
¹₃ of the total = 80 ÷ 2 = 40
³₃ of the total = 3 x 40 = 120

Number of stickers at first = 120

Answer(s): 120
