Three people share three bedrooms and one living room, the master bedroom, the second bedroom and the study. Rent 1 ***2000 yuan. How should it be distributed?

Share the public part equally: share it equally in 300 yuan.

If 900 yuan is deducted, the rent is still 1 100 yuan. Master bedroom 500 yuan, second bedroom 400 yuan, study 200 yuan.

Finally:

Lord, 300+500=800.

Time, 300+400=700.

Books, 300+200=500.
