A drink stall had 128 small and big bottles of orange juice. The number of small bottles is
313 of the number of big bottles. After selling a few big bottles of orange juice, there are
14 as many small bottles as big bottles left. How many big bottles of orange juice were sold?

The number of small bottles remains unchanged. Make the number of small bottles the same. LCM of 3 and 1 is 3.
Number of small bottles at first = 3 u
Number of big bottles at first = 13 u
Total number of bottles at first
= 3 u + 13 u
= 16 u
16 u = 128
1 u = 128 ÷ 16 = 8
Number of big bottles sold
= 13 u - 12 u
= 1 u
= 8
Answer(s): 8
