20100 =
1520% x 140
=
20100 x 140
= 28
50% x 28
=
50100 x 28
= 14
50% x 6 u
=
50100 x 6 u
= 3 u
Jenson had 354 less stickers than Neave in the end. If another 354 stickers are given to Jenson, both will have the same number of stickers.
7 u + 126 = 3 u + 14 + 354
7 u - 3 u = 14 + 354 - 126
4 u = 242
1 u = 242 ÷ 4 = 22
Number of Jenson's stickers at first
= 5 u
= 5 x 22
= 110
Answer: 110
