Difference = 2200 × 72% - 2000 × 75%
= 1584 – 1500
= 84
% more = (2100 × 54% + 2450 × 60% - 2000 × 75%) ÷ 2000 × 75% × 100
= (1134 + 1470 – 1500) ÷ 1500 × 100
= 1104 ÷ 15 = 73.6%
The students who qualified in school Y in 2013 = 2650 × 64% = 1696
Men = 1696 ÷ 8 × 5 = 1060
Ratio = 2100 × 54% + 2360 × 75% : 2320 × 60% + 2000 × 75%
= 1134 + 1770 : 1392 + 1500
= 2904 : 2892
= 242:241
Sum = 2450 × 60% + 2300 × 50% = 1470 + 1150
= 2620
