Vaidev had some blueberry muffins and apple muffins. He gave away 95 muffins to his sister. 40% of them were blueberry muffins and the rest were apple muffins.

1. How many apple muffins did he give his sister?
2. Vaidev gave some blueberry muffins to his cousin. ⁴₇ of all the muffins he gave away to his sister and his cousin were blueberry muffins. How many blueberry muffins did he give his cousin?

(a)
Percentage of apple muffins
= 100% - 40%
= 60%

Number of apple muffins that Vaidev gave to his sister
= 60% x 95
= ⁶⁰₁₀₀ x 95
= 57 

(b)
Fraction of all the muffins he gave away to his sister and his cousin that were apple muffins
= 1 - ⁴₇
= ³₇

3 u = 57

1 u = 57 ÷ 3 = 19

Number of blueberry muffins that Vaidev gave to his sister and his cousin
= 4 u
= 4 x 19
= 76

Number of blueberry muffins that Vaidev gave to his sister
= 95 - 57
= 38

Number of blueberry muffins that Vaidev gave to his cousin
= 76 - 38
= 38

Answer(s): (a) 57; (b) 38
