प्रयुक्त अवधारणा:
औसत = \( {\sum x_i\over n}\)
जहाँ n संस्थाओं की संख्या है।
गणना:
J 1 = \({sales \ of \ bikes \ by(P+Q+R)\over3 }\)
जे 1 = \({200+100+500\over3 }\)
जे 1 = \({800\over3}\)
अब, J 2 = \({sales \ of \ cars \ by(S+R+T)\over3 }\)
J2 = \({1000+700+800\over3}\)
J2 = \({2500\over3}\)
J 1 : J 2 = \({800\over3}\) : \(2500\over3\)
⇒ 8 : 25
∴ J 1 :J 2 का मान '8 : 25' है।
