Questions & Answers about क्या आपके सवाल का जवाब इस कागज़ पर है?
Here क्या is a yes/no question marker, not the word what.
So:
- क्या आपके सवाल का जवाब इस कागज़ पर है? = Is the answer to your question on this paper?
In other sentences, क्या can mean what, but when it appears at the beginning like this, it often just signals that the whole sentence is a yes/no question.
You can sometimes ask a yes/no question without क्या, using rising intonation instead, but क्या is very common and clear.
Because आपका / आपकी / आपके changes to agree with the noun that follows.
Here it is connected to सवाल:
- आपके सवाल = your question
The important point is that सवाल is in the oblique form here, because it is followed by का in सवाल का जवाब.
So the possessive must also take the oblique masculine form:
- आपका सवाल = your question
- आपके सवाल का जवाब = the answer to your question
Even though सवाल itself does not visibly change here, the form आपके shows that oblique relationship.
