Mrs Loh baked some puffs of three flavours, which were vanilla, chocolate chip and banana. She baked four times as many vanilla puffs as chocolate chip puffs and thrice as many banana puffs as vanilla puff. Given that she baked 66 more banana puffs than chocolate chip puffs, how many puffs did she bake?
Number of chocolate chip puffs = 1 u
Number of vanilla puffs = 4 u
Number of banana puffs = 3 x 4 u = 12 u

Number of more banana puffs than chocolate chip puffs
= 12 u - 1 u 
= 11 u

11 u = 66

1 u = 66 ÷ 11 = 6

Number of vanilla puffs
= 4 u
= 4 x 6
= 24

Number of banana puffs
= 12 u
= 12 x 6
= 72

Total number of puffs that he baked
= 6 + 24 + 72
= 102

Answer(s): 102
