25% =
25100 =
1425% x 140
=
25100 x 140
= 35
80% x 35
=
80100 x 35
= 28
80% x 5 u
=
80100 x 5 u
= 4 u
Justin had 294 less stickers than Flynn in the end. If another 294 stickers are given to Justin, both will have the same number of stickers.
7 u + 133 = 1 u + 7 + 294
7 u - 1 u = 7 + 294 - 133
6 u = 168
1 u = 168 ÷ 6 = 28
Number of Justin's stickers at first
= 4 u
= 4 x 28
= 112
Answer: 112
