Adam has some stickers
He gives away ¹₃ and an additional 39 stickers to Bryan.
He gives away ⁵₉ of the remainder and 18 more stickers to Chris
and ³₅ 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 + 39
Number of stickers that Adam gives to Chris = ⁵₉ of the remainder + 18
Number of stickers that Adam gives to David = ³₅ of the rest
Number of stickers left = 4


Working backwards.
1 - ³₅ = ²₅

²₅ of the rest → 4
¹₅ of the rest → 4 ÷ 2 = 2
⁵₅ of the rest → 5 x 2 = 10

1 - ⁵₉ = ⁴₉

⁴₉ of the remainder = 18 + 10 = 28
¹₉ of the remainder = 28 ÷ 4 = 7
⁹₉ of the remainder = 9 x 7 = 63

1 - ¹₃ = ²₃
²₃ of the total = 63 + 39 = 102
¹₃ of the total = 102 ÷ 2 = 51
³₃ of the total = 3 x 51 = 153

Number of stickers at first = 153

Answer(s): 153
