The local deli serves pasta salad, every four days and pretzel salad every six days. If pasta, salad and pretzel salad are both on today’s menu, how many days before they are both on the menu again

To determine when both pasta salad and pretzel salad will be on the menu again, we need to find the least common multiple (LCM) of 4 and 6.

The multiples of 4 are: 4, 8, 12, 16, 20, 24...
And the multiples of 6 are: 6, 12, 18, 24...

The least common multiple of 4 and 6 is 12.

Therefore, it will take 12 days before both pasta salad and pretzel salad are on the menu again.
