P, Q, R, S, T, V and W are seven members of a family. Each one of them has a different profession — doctor, teacher, lawyer, engineer, architect, chartered accountant and banker — and their incomes are different. There are two married couples in the group. R is the doctor and earns more than the engineer and the lawyer. T is married to the chartered accountant and she earns the least. No lady is either a lawyer or an engineer. Q, the teacher, earns less than P, the banker. W is married to Q and he earns more than S and P. V is not the lawyer. The chartered accountant earns less than the lawyer but more than the banker. How many male members are there in the family?
