Sam had some strawberry tarts and cherry tarts. He gave away 96 tarts to his cousin. 25% of them were strawberry tarts and the rest were cherry tarts.
- How many cherry tarts did he give his cousin?
- Sam gave some strawberry tarts to his brother. 25 of all the tarts he gave away to his cousin and his brother were strawberry tarts. How many strawberry tarts did he give his brother?
(a)
Percentage of cherry tarts
= 100% - 25%
= 75%
Number of cherry tarts that Sam gave to his cousin
= 75% x 96
=
75100 x 96
= 72
(b)
Fraction of all the tarts he gave away to his cousin and his brother that were cherry tarts
= 1 -
25=
353 u = 72
1 u = 72 ÷ 3 = 24
Number of strawberry tarts that Sam gave to his cousin and his brother
= 2 u
= 2 x 24
= 48
Number of strawberry tarts that Sam gave to his cousin
= 96 - 72
= 24
Number of strawberry tarts that Sam gave to his brother
= 48 - 24
= 24
Answer(s): (a) 72; (b) 24
