Show answer & explanation

Correct answer: B

Step-by-Step Calculation
Extract Data:

Invested Amounts: 120, 225, 375, 330, 525

Sales Values: 200, 300, 500, 400, 600

Calculate J1 (Average Investment):

Sum of investments = 120 + 225 + 375 + 330 + 525 = 1575

J1 = 1575 / 5 = 315

Calculate J2 (Average Sales):

Sum of sales = 200 + 300 + 500 + 400 + 600 = 2000

J2 = 2000 / 5 = 400

Calculate J3 (Difference in 2005):

Invested in 2005 = 330

Sales in 2005 = 400

J3 = 400 - 330 = 70

Final Calculation:

J2 – J1 + J3 = 400 – 315 + 70

85 + 70 = 155
