Adam has some stickers
He gives away ¹₄ and an additional 63 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 16 stickers left.
How many stickers does he have at first?
Number of stickers that Adam gives to Bryan = ¹₄ of the total + 63
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 = 16


Working backwards.
1 - ³₇ = ⁴₇

⁴₇ of the rest → 16
¹₇ of the rest → 16 ÷ 4 = 4
⁷₇ of the rest → 7 x 4 = 28

1 - ³₁₀ = ⁷₁₀

⁷₁₀ of the remainder = 14 + 28 = 42
¹₁₀ of the remainder = 42 ÷ 7 = 6
¹⁰₁₀ of the remainder = 10 x 6 = 60

1 - ¹₄ = ³₄
³₄ of the total = 60 + 63 = 123
¹₄ of the total = 123 ÷ 3 = 41
⁴₄ of the total = 4 x 41 = 164

Number of stickers at first = 164

Answer(s): 164
