A drink stall had 110 big and small bottles of soy milk. The number of big bottles is
29 of the number of small bottles. After selling a few small bottles of soy milk, there are
14 as many big bottles as small bottles left. How many small bottles of soy milk were sold?

The number of big bottles remains unchanged. Make the number of big bottles the same. LCM of 2 and 1 is 2.
Number of big bottles at first = 2 u
Number of small bottles at first = 9 u
Total number of bottles at first
= 2 u + 9 u
= 11 u
11 u = 110
1 u = 110 ÷ 11 = 10
Number of small bottles sold
= 9 u - 8 u
= 1 u
= 10
Answer(s): 10
