Xavier had some cheese muffins and apricot muffins. He gave away 184 muffins to his brother. 25% of them were cheese muffins and the rest were apricot muffins.
- How many apricot muffins did he give his brother?
- Xavier gave some cheese muffins to his sister. 47 of all the muffins he gave away to his brother and his sister were cheese muffins. How many cheese muffins did he give his sister?
(a)
Percentage of apricot muffins
= 100% - 25%
= 75%
Number of apricot muffins that Xavier gave to his brother
= 75% x 184
=
75100 x 184
= 138
(b)
Fraction of all the muffins he gave away to his brother and his sister that were apricot muffins
= 1 -
47=
373 u = 138
1 u = 138 ÷ 3 = 46
Number of cheese muffins that Xavier gave to his brother and his sister
= 4 u
= 4 x 46
= 184
Number of cheese muffins that Xavier gave to his brother
= 184 - 138
= 46
Number of cheese muffins that Xavier gave to his sister
= 184 - 46
= 138
Answer(s): (a) 138; (b) 138
