Mrs Neo baked some muffins of three flavours, which were vanilla, cranberry and apricot. She baked thrice as many vanilla muffins as cranberry muffins and thrice as many apricot muffins as vanilla muffin. Given that she baked 88 more apricot muffins than cranberry muffins, how many muffins did she bake?
Number of cranberry muffins = 1 u
Number of vanilla muffins = 3 u
Number of apricot muffins = 3 x 3 u = 9 u

Number of more apricot muffins than cranberry muffins
= 9 u - 1 u 
= 8 u

8 u = 88

1 u = 88 ÷ 8 = 11

Number of vanilla muffins
= 3 u
= 3 x 11
= 33

Number of apricot muffins
= 9 u
= 9 x 11
= 99

Total number of muffins that he baked
= 11 + 33 + 99
= 143

Answer(s): 143
