To solve we can create a fairly simple word translation. Remember if we are asked “x is what percent of y”? we can set up the following expression:

x/y * 100 = ?

In this problem we are asked '150 is what percent of 30' and we can solve this by substituting 150 for x and 30 for y:

150/30 x 100 = ?

5 x 100 = 500%

as we need to find out what percentage 150 is of 30, we can quickly cancel out options A-C as we need to find a value higher than 100%.

200% of 30 is 60.

We are left with 500%. E
