Adam has some stickers
He gives away ¹₄ and an additional 78 stickers to Bryan.
He gives away ¹₁₀ of the remainder and 12 more stickers to Chris
and ⁴₇ of the rest to David.
Adam has 18 stickers left.
How many stickers does he have at first?
Number of stickers that Adam gives to Bryan = ¹₄ of the total + 78
Number of stickers that Adam gives to Chris = ¹₁₀ of the remainder + 12
Number of stickers that Adam gives to David = ⁴₇ of the rest
Number of stickers left = 18


Working backwards.
1 - ⁴₇ = ³₇

³₇ of the rest → 18
¹₇ of the rest → 18 ÷ 3 = 6
⁷₇ of the rest → 7 x 6 = 42

1 - ¹₁₀ = ⁹₁₀

⁹₁₀ of the remainder = 12 + 42 = 54
¹₁₀ of the remainder = 54 ÷ 9 = 6
¹⁰₁₀ of the remainder = 10 x 6 = 60

1 - ¹₄ = ³₄
³₄ of the total = 60 + 78 = 138
¹₄ of the total = 138 ÷ 3 = 46
⁴₄ of the total = 4 x 46 = 184

Number of stickers at first = 184

Answer(s): 184
