Let a person's income be X and his expenditure be Y; Then the other party's income is 3/4x and the expenditure is 13/ 18y.

Judging from the meaning of the question:

x-y=360

3/4x- 13/ 18y=360

By solving the equation, we can get:

x = 3600y=3240

3600×3/4=2700; 3240× 13/ 18=2340

So:

A person's income is 3600 yuan; The other party earns 2700 yuan.

A person's expenditure is 3240 yuan; The other party spends 2340 yuan.
