Dear Student,

we will count the number of times each marble is repeatedHence we get P+2Q=660  --1Q+R+S=600  --2P+S+R=540  --3Subtract equation 3 from 2Q-P=600-540Q-P=60 --4now we have two equationsP+2Q=660  --1Q-P=60 --4add both equationsP+2Q+Q-P=660+603Q=720Q=7203Q=240Put this value in equation 4240-P=60P=240-60P=180
Hence option C is correct
