Explanation

Step 1: Calculate 172.5% of 415 = 1.725 × 415 = 715.875. Step 2: Calculate 72.5% of 650 = 0.725 × 650 = 471.25. Step 3: Set up equation: 715.875 - (x% of 192) = 471.25. Therefore: x% of 192 = 715.875 - 471.25 = 244.625. Step 4: x = (244.625/192) × 100 = 127.4%. Among the options, 130 is the closest.
