Mrs Leng baked some shortbreads of three flavours, which were cherry, strawberry and chocolate chip. She baked thrice as many cherry shortbreads as strawberry shortbreads and twice as many chocolate chip shortbreads as cherry shortbread. Given that she baked 85 more chocolate chip shortbreads than strawberry shortbreads, how many shortbreads did she bake?
Number of strawberry shortbreads = 1 u
Number of cherry shortbreads = 3 u
Number of chocolate chip shortbreads = 2 x 3 u = 6 u

Number of more chocolate chip shortbreads than strawberry shortbreads
= 6 u - 1 u 
= 5 u

5 u = 85

1 u = 85 ÷ 5 = 17

Number of cherry shortbreads
= 3 u
= 3 x 17
= 51

Number of chocolate chip shortbreads
= 6 u
= 6 x 17
= 102

Total number of shortbreads that he baked
= 17 + 51 + 102
= 170

Answer(s): 170
