A drink stall had 187 small and big packets of orange juice. The number of small packets is
314 of the number of big packets. After selling a few big packets of orange juice, there are
14 as many small packets as big packets left. How many big packets of orange juice were sold?

The number of small packets remains unchanged. Make the number of small packets the same. LCM of 3 and 1 is 3.
Number of small packets at first = 3 u
Number of big packets at first = 14 u
Total number of packets at first
= 3 u + 14 u
= 17 u
17 u = 187
1 u = 187 ÷ 17 = 11
Number of big packets sold
= 14 u - 12 u
= 2 u
= 2 x 11
= 22
Answer(s): 22
