College A B C D E Demand (application received) 3000 600 2500 1200 3300 Intake…

First, identify the demand values for each college: A=3000, B=600, C=2500, D=1200, E=3300. The two highest demands are from College E (3300) and College A (3000), summing to 6300. The two lowest demands are from College B (600) and College D (1200), summing to 1800. To find how much higher the highest total is compared to the lowest, calculate the difference: 6300 - 1800 = 4500. Then, express this difference as a percentage of the lowest total: (4500 / 1800) × 100 = 2.5 × 100 = 250%. Thus, the total demand of the two highest colleges is 250% higher than that of the two lowest. Options A (40%) and C (400%) result from incorrect summation or division errors, while D (25%) likely stems from misplacing the decimal point.
