A drink stall had 102 big and small bottles of water. The number of big bottles is
314 of the number of small bottles. After selling a few small bottles of water, there are
14 as many big bottles as small bottles left. How many small bottles of water were sold?

Big bottles |
Small bottles |

- 2 u |

After |
1x3 = 3 u |
4x3 = 12 u |

The number of big bottles remains unchanged. Make the number of big bottles the same. LCM of 3 and 1 is 3.
Number of big bottles at first = 3 u
Number of small 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 small bottles sold
= 14 u - 12 u
= 2 u
= 2 x 6
= 12
Answer(s): 12
