Jeremy had some apricot scones and vanilla scones. He gave away 190 scones to his sister. 20% of them were apricot scones and the rest were vanilla scones.

1. How many vanilla scones did he give his sister?
2. Jeremy gave some apricot scones to his brother. ³₅ of all the scones he gave away to his sister and his brother were apricot scones. How many apricot scones did he give his brother?

(a)
Percentage of vanilla scones
= 100% - 20%
= 80%

Number of vanilla scones that Jeremy gave to his sister
= 80% x 190
= ⁸⁰₁₀₀ x 190
= 152 

(b)
Fraction of all the scones he gave away to his sister and his brother that were vanilla scones
= 1 - ³₅
= ²₅

2 u = 152

1 u = 152 ÷ 2 = 76

Number of apricot scones that Jeremy gave to his sister and his brother
= 3 u
= 3 x 76
= 228

Number of apricot scones that Jeremy gave to his sister
= 190 - 152
= 38

Number of apricot scones that Jeremy gave to his brother
= 228 - 38
= 190

Answer(s): (a) 152; (b) 190
