Answer and explanation

Correct answer C

Group III of city D is 48×12.8=6.4\frac{4}{8}\times12.8 = 6.4 lakh, and group II of city B is 38×16=6\frac{3}{8}\times16 = 6 lakh. The excess is 0.4 lakh, and 0.4/6×100=623%0.4/6\times100 = 6\frac{2}{3}\%. Dividing by 6.4 instead gives 614%6\frac{1}{4}\%, but "more than" is measured against the smaller figure, 6 lakh.
