A drink stall had 143 big and small packets of juice. The number of big packets is
211 of the number of small packets. After selling a few small packets of juice, there are
14 as many big packets as small packets left. How many small packets of juice were sold?

The number of big packets remains unchanged. Make the number of big packets the same. LCM of 2 and 1 is 2.
Number of big packets at first = 2 u
Number of small packets at first = 11 u
Total number of packets at first
= 2 u + 11 u
= 13 u
13 u = 143
1 u = 143 ÷ 13 = 11
Number of small packets sold
= 11 u - 8 u
= 3 u
= 3 x 11
= 33
Answer(s): 33
