Adam has some stickers
He gives away ¹₃ and an additional 73 stickers away to Bryan.
He gives away 5 less than ⁵₇ of the remaining stickers to Chris
and ²₅ of the rest to David.
Adam has 9 stickers left.
How many stickers does he have at first?
Number of stickers that Adam gives to Bryan = ¹₃ of the total + 73
Number of stickers that Adam gives to Chris = ⁵₇ of the remainder - 5
Number of stickers that Adam gives to David = ²₅ of the rest
Number of stickers left = 9


Working backwards.
1 - ²₅ = ³₅

³₅ of the rest = 9
¹₅ of the rest = 9 ÷ 3 = 3
⁵₅ of the rest = 5 x 3 = 15

1 - ⁵₇ = ²₇

²₇ of the remainder = 15 - 5 = 10
¹₇ of the remainder = 10 ÷ 2 = 5
⁷₇ of the remainder = 7 x 5 = 35

1 - ¹₃ = ²₃
²₃ of the total = 35 + 73 = 108
¹₃ of the total = 108 ÷ 2 = 54
³₃ of the total = 3 x 54 = 162

Number of stickers at first = 162

Answer(s): 162
