Ahmad had some cherry puffs and banana puffs. He gave away 180 puffs to his sister. 30% of them were cherry puffs and the rest were banana puffs.
- How many banana puffs did he give his sister?
- Ahmad gave some cherry puffs to his cousin. 47 of all the puffs he gave away to his sister and his cousin were cherry puffs. How many cherry puffs did he give his cousin?
(a)
Percentage of banana puffs
= 100% - 30%
= 70%
Number of banana puffs that Ahmad gave to his sister
= 70% x 180
=
70100 x 180
= 126
(b)
Fraction of all the puffs he gave away to his sister and his cousin that were banana puffs
= 1 -
47=
373 u = 126
1 u = 126 ÷ 3 = 42
Number of cherry puffs that Ahmad gave to his sister and his cousin
= 4 u
= 4 x 42
= 168
Number of cherry puffs that Ahmad gave to his sister
= 180 - 126
= 54
Number of cherry puffs that Ahmad gave to his cousin
= 168 - 54
= 114
Answer(s): (a) 126; (b) 114
