A19

B20

C18

D21

Answer:

A. 19

Read Explanation:

ആകെ ആളുകൾ = മുന്നിൽ നിന്നുള്ള സ്ഥാനം+ പുറകിൽ നിന്നുള്ള സ്ഥാനം - 1 = 13+7-1=19 മുന്നിൽ നിന്നുള്ള സ്ഥാനവും പുറകിൽ നിന്നുള്ള സ്ഥാനവും കണക്കാക്കുമ്പോൾ 2 തവണ രാമുവിനെ എണ്ണുന്നു അതിനാൽ ആകെ ആളുകളെ കണക്കാക്കാൻ മുന്നിൽ നിന്നുള്ള സ്ഥാനവും പുറകിൽ നിന്നുള്ള സ്ഥാനവും തമ്മിൽ കൂട്ടി 1 കുറക്കണം.
