The fewest number of vegetables that can be used to make this salad is 4
Therefore, option (3) is correct.
Step-by-step explanation:
Give ratios of carrots to cucumbers
3:9, 4:12, 6:18 and 7:21
We can see that the ratio of carrots and cucumbers is constant and this ratio is 1:3
Therefore, the salad can be prepared if we use only one carrot and 3 cucumbers
As the ratio of carrot to cucumber will still be 1:3
Therefore, total number of vegetables to be used = 1 + 3 = 4
