Mrs Yong baked some wafers of three flavours, which were chocolate chip, cherry and cranberry. She baked twice as many chocolate chip wafers as cherry wafers and twice as many cranberry wafers as chocolate chip wafer. Given that she baked 96 more cranberry wafers than cherry wafers, how many wafers did she bake?
Number of cherry wafers = 1 u
Number of chocolate chip wafers = 2 u
Number of cranberry wafers = 2 x 2 u = 4 u

Number of more cranberry wafers than cherry wafers
= 4 u - 1 u 
= 3 u

3 u = 96

1 u = 96 ÷ 3 = 32

Number of chocolate chip wafers
= 2 u
= 2 x 32
= 64

Number of cranberry wafers
= 4 u
= 4 x 32
= 128

Total number of wafers that he baked
= 32 + 64 + 128
= 224

Answer(s): 224
