మొత్తం పని = (6, 8 మరియు 3 యొక్క కనీస సామాన్య గుణకం) = 24 యూనిట్లు

కాబట్టి, P యొక్క సామర్థ్యం = 4

Q యొక్క సామర్థ్యం = 3

(P + Q + R) యొక్క సామర్థ్యం = 8

కాబట్టి, R యొక్క సామర్థ్యం = 8 - 4 - 3 = 1

P, Q మరియు R ల సామర్థ్య నిష్పత్తి = 4 : 3 : 1

మొత్తం వేతనం = రూ. 3200

∴ వేతనాల్లో R యొక్క వాటా = 3200 x (1/8) = రూ. 400
