Worked Solution

Step 1: Write an equation using the given information. Dividing by 100 gives a larger result than dividing by 1000, so: P/100 - P/1000 = 0.594 Step 2: Express both fractions with a common denominator of 1000. 10P/1000 - P/1000 = 0.594 9P/1000 = 0.594 Step 3: Solve for P. 9P = 0.594 x 1000 = 594 P = 594 / 9 = 66 Verification: 66 / 100 = 0.66 and 66 / 1000 = 0.066. Difference = 0.66 - 0.066 = 0.594. Check.

Correct answer: 66
