Mrs Yee baked some shortbreads of three flavours, which were cherry, vanilla and blueberry. She baked twice as many cherry shortbreads as vanilla shortbreads and thrice as many blueberry shortbreads as cherry shortbread. Given that she baked 65 more blueberry shortbreads than vanilla shortbreads, how many shortbreads did she bake?
Number of vanilla shortbreads = 1 u
Number of cherry shortbreads = 2 u
Number of blueberry shortbreads = 3 x 2 u = 6 u

Number of more blueberry shortbreads than vanilla shortbreads
= 6 u - 1 u 
= 5 u

5 u = 65

1 u = 65 ÷ 5 = 13

Number of cherry shortbreads
= 2 u
= 2 x 13
= 26

Number of blueberry shortbreads
= 6 u
= 6 x 13
= 78

Total number of shortbreads that he baked
= 13 + 26 + 78
= 117

Answer(s): 117
