A drink stall had 102 small and big bottles of green tea. The number of small bottles is
314 of the number of big bottles. After selling a few big bottles of green tea, there are
14 as many small bottles as big bottles left. How many big bottles of green tea 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 = 14 u
Total number of bottles at first
= 3 u + 14 u
= 17 u
17 u = 102
1 u = 102 ÷ 17 = 6
Number of big bottles sold
= 14 u - 12 u
= 2 u
= 2 x 6
= 12
Answer(s): 12
