A_{1}+B_{1}+C_{1}=24.36+0.0724+256.2=280.6324=280.6A_{2}+B_{2}+C_{2}=24.44+16.082+240.2=280.722=280.7A_{3}+B_{3}+C_{3}=25.2+19.2812+236.183=280.6642=280.7A_{4}+B_{4}+C_{4}=25+236.191+19.5=280.691=281

Answer should be A_{1}+B_{1}+C_{1}< A_{2}+B_{2}+C_{2}=A_{3}+B_{3}+C_{3}< A_{4}+B_{4}+C_{4}

So option (4) is correct.
