Correct answer

8888

Explanation

Convert percentages to fractions: 62.5%=58    58×1472=5×184=92062.5\% = \frac{5}{8} \implies \frac{5}{8} \times 1472 = 5 \times 184 = 920. 87.5%=78    78×1152=7×144=100887.5\% = \frac{7}{8} \implies \frac{7}{8} \times 1152 = 7 \times 144 = 1008. 43.75%=50%6.25%=12116=716    716×1792=7×112=78443.75\% = 50\% - 6.25\% = \frac{1}{2} - \frac{1}{16} = \frac{7}{16} \implies \frac{7}{16} \times 1792 = 7 \times 112 = 784. LHS: 920+1008784=1144920 + 1008 - 784 = 1144. 1144=?×13    ?=114413=881144 = ? \times 13 \implies ? = \frac{1144}{13} = 88.
