In addition using significant figures, we need to round off to least decimal points.​$$A1+B1+C1=24.36+0.0724+256.2=280.6324=280.6s$$  Using significant $$figureA2+B2+C2=24.44+16.082+240.2=280.722$$ $$=280.7$$​$$A3+B3+C3=25.2+19.2812+236.183=280.6642$$ $$=280.7$$​$$A4+B4+C4=25+236.191+19.5=280.691$$ $$=281$$
