Adam has some stickers
He gives away ¹₄ and an additional 57 stickers to Bryan.
He gives away ²₅ of the remainder and 19 more stickers to Chris
and ⁴₇ 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 = ¹₄ of the total + 57
Number of stickers that Adam gives to Chris = ²₅ of the remainder + 19
Number of stickers that Adam gives to David = ⁴₇ of the rest
Number of stickers left = 15


Working backwards.
1 - ⁴₇ = ³₇

³₇ of the rest → 15
¹₇ of the rest → 15 ÷ 3 = 5
⁷₇ of the rest → 7 x 5 = 35

1 - ²₅ = ³₅

³₅ of the remainder = 19 + 35 = 54
¹₅ of the remainder = 54 ÷ 3 = 18
⁵₅ of the remainder = 5 x 18 = 90

1 - ¹₄ = ³₄
³₄ of the total = 90 + 57 = 147
¹₄ of the total = 147 ÷ 3 = 49
⁴₄ of the total = 4 x 49 = 196

Number of stickers at first = 196

Answer(s): 196
