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 Charted Accountant and she earns the least.No lady is either Lawyer or 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.

I am getting answer as $3)R$

Since, R= doctor , Q=Teacher, P=Banker. T is married to CA(chartered accountant) and "she" is used for female.So, T is female. T can't be lawyer or engineer and also can't be CA because she got married with him. So, "T" MUST be Architect who earns least. Doctor earns more than engineer and lawyer. Teacher earns less than banker and CA earns learns less than lawyer and more than banker.Now, Based on these 2 facts , we can say Doctor $R$ earns maximum in the family.

@Deterministic

It is given that R= Doctor , Q=Teacher, P=Banker and as I said in comment T must be architect..

Now, W can be lawyer or engineer or CA

Since, It is given that "Doctor earns more than engineer and lawyer" and " CA earns learns less than lawyer and more than banker"

So,  W can't earn maximum salary..

Why architect cannot get maximum salary?
0

according to question,

$Q,T$ are girls and all others are boys.

$P$-Banker

$Q$-Teacher

$R$-Doctor

$V$-Not Law-yer

Banker >Teacher

Lawyer > Charted-Accountant > Banker.

Doctor > Engineer and Law-yer

T has lowest income.

Now, Highest can be among Doctor and Architect

and lowest can be among Engineer and Architect.

Now, tell me how u got Doctor has highest salary and not Architect??

Why architect cannot get maximum salary?

Because it is given in question "T is married to the Charted Accountant and she earns the least". As I said T is architect and she earns least.

Now, tell me how u got Doctor has highest salary and not Architect??
