Questions & Answers about इस सवाल का हल आसान है।
इस means this here, but specifically in its oblique form.
In Hindi, यह changes to इस when it comes before a noun that is connected to a postposition or a postposition-like marker later in the noun phrase. Since the phrase is इस सवाल का (of this question), Hindi uses इस, not यह.
Compare:
- यह सवाल = this question
- इस सवाल का हल = the solution of this question
So यह is the basic form, and इस is the form used in constructions like this one.
सवाल means question.
It is a very common everyday word. A more formal Sanskrit-based word is प्रश्न, which also means question.
So these are both possible:
- इस सवाल का हल आसान है।
- इस प्रश्न का हल आसान है।
The first sounds more everyday and conversational.
हल means solution or way to solve.
It is often used for something like a problem, exercise, puzzle, or question that has to be worked out.
