क्या यह काम मुश्किल है, या तुम यह काम कर सकती हो?

At the beginning of a sentence, क्या often marks a yes/no question.

So:

• क्या यह काम मुश्किल है...? = Is this work difficult...?

This is different from क्या meaning what in other contexts.
For example:

• यह क्या है? = What is this?

So in your sentence, क्या is not what. It is a question marker.

Hindi often repeats the noun where English might use it.

So:

• क्या यह काम मुश्किल है, या तुम यह काम कर सकती हो?

literally keeps this work / this task in both parts. In English, we would usually say:

• Is this task difficult, or can you do it?

In Hindi, repeating यह काम sounds natural and clear. You could sometimes omit the second यह काम if the meaning is obvious, but repetition is very common.

मुश्किल means difficult or hard, and है means is.

Together:

• मुश्किल है = is difficult

Hindi often uses this pattern:

• noun + adjective + है

So:

• यह काम मुश्किल है = This task is difficult

Unlike in English, you do not need a separate word like very or too unless you want to add it.

या means or.

It connects two alternatives:

• क्या यह काम मुश्किल है, या तुम यह काम कर सकती हो?
• Is this task difficult, or can you do this task?

So the speaker is presenting two possibilities:

1. the task is difficult, or
2. the person can do it

Hindi has different levels of you:

• तू = very intimate / very informal / sometimes rude depending on context
• तुम = informal but normal and common
• आप = polite / formal / respectful

So तुम suggests the speaker is talking to someone familiar, such as a friend, younger person, sibling, or someone they speak casually with.

If you wanted a more polite version, you could say:

• क्या यह काम मुश्किल है, या आप यह काम कर सकती हैं?

Because सकती is the feminine singular form.

This tells you the person being addressed is female.

• तुम ... कर सकती ho = you (female) can do
• तुम ... कर सकते ho = you (male / mixed group) can do

So this sentence is addressed to a woman or girl.

This is a very common Hindi pattern for ability:

• main verb stem + सकना
  • appropriate ending

Here:

• कर = do
• सकती = able/can (feminine form)
• हो = are

So:

• कर सकती हो literally means something like are able to do
• natural English: can do

Examples:

• तुम यह कर सकती हो। = You can do this.
• वह तैर सकता है। = He can swim.

हो is the form of to be used with तुम.

Compare:

• मैं ... सकता हूँ = I can
• तुम ... सकती हो = you can
• वह ... सकता है = he can
• आप ... सकती हैं = you can (polite, feminine)

So in कर सकती हो, the हो matches तुम.

It is contrasting the two ideas.

The sentence basically says:

• Is this task difficult, or can you do it?

That can sound slightly unusual in English depending on context, but in Hindi it can suggest something like:

• Is it really difficult, or are you able to handle it?
• Is this task hard, or can you do it anyway?

So the speaker is checking both:

1. whether the task is difficult, and
2. whether the listener is capable of doing it

Hindi usually follows Subject-Object-Verb order more than English does.

A rough breakdown:

• क्या = question marker
• यह काम = this task
• मुश्किल है = is difficult
• या = or
• तुम = you
• यह काम = this task
• कर सकती हो = can do

So the second part is literally:

• you this task can do

That is normal Hindi structure.

Yes. Depending on context, speakers might choose slightly different wording.

For example:

• क्या यह काम मुश्किल है, या तुम इसे कर सकती हो?
  = Is this task difficult, or can you do it?

Here इसे means it and avoids repeating यह काम.

Another possible phrasing:

• क्या यह काम मुश्किल है, या तुम कर सकती हो?
  = Is this task difficult, or can you do it?

This is shorter and works if the task is already clear from context.

But the original sentence is still understandable and grammatically fine.

You would change सकती to सकते:

• क्या यह काम मुश्किल है, या तुम यह काम कर सकते हो?

That means:

• Is this task difficult, or can you do this task?
  addressed to a male listener

If speaking politely to a woman:

• क्या यह काम मुश्किल है, या आप यह काम कर सकती हैं?

If speaking politely to a man:

• क्या यह काम मुश्किल है, या आप यह काम कर सकते हैं?

Yes. काम has a broad meaning.

Depending on context, it can mean:

• work
• task
• job
• thing to be done

In this sentence, task is often the most natural English choice, because the speaker seems to be talking about a specific piece of work:

• यह काम = this task / this work

So the exact English word depends on context, but काम itself is very common and flexible.
