Adam buys some stickers for his friends.
If he gives each of them 6 stickers, he has 5 stickers left.
If he gives each of them 10 stickers, he needs another 19.
- How many friends are there?
- How many stickers does Adam buy?
(a)
Big difference
= 5 + 19
= 24
Small difference
= 10 - 6
= 4
Number of friends that Adam gives to
= 24 ÷ 4
= 6
(b)
Number of stickers that Adam buys
= 6 x 6 + 5
= 36 + 5
= 41
Answer(s): (a) 6; (b) 41
