A drink stall had 112 small and big bottles of juice. The number of small bottles is
311 of the number of big bottles. After selling a few big bottles of juice, there are
13 as many small bottles as big bottles left. How many big bottles of 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 = 11 u
Total number of bottles at first
= 3 u + 11 u
= 14 u
14 u = 112
1 u = 112 ÷ 14 = 8
Number of big bottles sold
= 11 u - 9 u
= 2 u
= 2 x 8
= 16
Answer(s): 16
