Ahmad had some blueberry puffs and banana puffs. He gave away 112 puffs to his brother. 25% of them were blueberry puffs and the rest were banana puffs.
- How many banana puffs did he give his brother?
- Ahmad gave some blueberry puffs to his cousin. 47 of all the puffs he gave away to his brother and his cousin were blueberry puffs. How many blueberry puffs did he give his cousin?
(a)
Percentage of banana puffs
= 100% - 25%
= 75%
Number of banana puffs that Ahmad gave to his brother
= 75% x 112
=
75100 x 112
= 84
(b)
Fraction of all the puffs he gave away to his brother and his cousin that were banana puffs
= 1 -
47=
373 u = 84
1 u = 84 ÷ 3 = 28
Number of blueberry puffs that Ahmad gave to his brother and his cousin
= 4 u
= 4 x 28
= 112
Number of blueberry puffs that Ahmad gave to his brother
= 112 - 84
= 28
Number of blueberry puffs that Ahmad gave to his cousin
= 112 - 28
= 84
Answer(s): (a) 84; (b) 84
