Adam has some stickers
He gives away ¹₅ and an additional 72 stickers to Bryan.
He gives away ⁵₈ of the remainder and 23 more stickers to Chris
and ²₅ of the rest to David.
Adam has 15 stickers left.
How many stickers does he have at first?
Number of stickers that Adam gives to Bryan = ¹₅ of the total + 72
Number of stickers that Adam gives to Chris = ⁵₈ of the remainder + 23
Number of stickers that Adam gives to David = ²₅ of the rest
Number of stickers left = 15


Working backwards.
1 - ²₅ = ³₅

³₅ of the rest → 15
¹₅ of the rest → 15 ÷ 3 = 5
⁵₅ of the rest → 5 x 5 = 25

1 - ⁵₈ = ³₈

³₈ of the remainder = 23 + 25 = 48
¹₈ of the remainder = 48 ÷ 3 = 16
⁸₈ of the remainder = 8 x 16 = 128

1 - ¹₅ = ⁴₅
⁴₅ of the total = 128 + 72 = 200
¹₅ of the total = 200 ÷ 4 = 50
⁵₅ of the total = 5 x 50 = 250

Number of stickers at first = 250

Answer(s): 250
