Answer: D

Solution:

We can let n = the total amount of tips and thus (2n/3)/4 = 2n/12 = n/6 is the amount that one waiter receives.

Since the waiters and managers receive 2/3 + 1/4 = 8/12 + 3/12 = 11/12 of the total tips, the busboy receives 1/12 of the total tips. Now we can create the equation:

n/12 + n/6 = 30

Multiplying the equation by 12, we have:

n + 2n = 360

3n = 360

n = 120
