बाज़ार में यह किताब सस्ती है, लेकिन स्टेशन की दुकान में इसकी कीमत ज़्यादा है।

Because किताब is a feminine noun in Hindi, and the adjective must agree with it.

• सस्ता = masculine singular
• सस्ती = feminine singular
• सस्ते = masculine plural / some oblique uses

So:

• यह किताब सस्ती है = This book is cheap

If the noun were masculine, you would use सस्ता:

• यह बैग सस्ता है = This bag is cheap

में means in or at, depending on context.

In this sentence:

• बाज़ार में = in the market
• स्टेशन की दुकान में = in the station shop / at the shop in the station

It appears twice because there are two different location phrases, one in each clause.

So the structure is roughly:

• [place] में + [statement]
• [another place] में + [statement]

Because दुकान is feminine, and का / की / के agree with the noun that follows.

Here:

• दुकान = shop, feminine
• so you need की

That gives:

• स्टेशन की दुकान = the station's shop / the shop at the station

Compare:

• लड़के का बैग = the boy's bag (बैग is masculine)
• लड़के की किताब = the boy's book (किताब is feminine)

So की is used because दुकान is feminine.

This is a very common pattern in Hindi.

• यह = this
• इसकी = its / of this

More exactly, इसकी comes from यह changing to the oblique stem इस-, and then taking the possessive ending -की.

Why -की? Because the thing possessed is कीमत, and कीमत is feminine.

So:

• यह किताब = this book
• इसकी कीमत = its price / the price of this

You could expand it fully as:

• इस किताब की कीमत = the price of this book

But इसकी कीमत is shorter and more natural once किताब has already been mentioned.

इसकी कीमत means its price or the price of this.

Breakdown:

• इसकी = its / of this
• कीमत = price

So:

• इसकी कीमत ज़्यादा है = its price is higher / its price is more

This refers back to यह किताब from the first part of the sentence.

Both are possible, but they are slightly different in emphasis.

• यह किताब महंगी है = this book is expensive
• इसकी कीमत ज़्यादा है = its price is higher

The sentence you were given contrasts two places and focuses specifically on price. That makes कीमत a natural choice.

So the sentence is doing this:

• In the market, the book is cheap
• But in the station shop, its price is higher

A simpler version could be:

• बाज़ार में यह किताब सस्ती है, लेकिन स्टेशन की दुकान में यह महंगी है।

That is also correct, but the original sounds a little more precise.

Good question. Hindi often uses ज़्यादा for a comparison that is understood from context, even without an explicit से phrase.

Here, the first clause already tells you the market price is low, and the second clause says the price at the station shop is higher. The comparison is understood.

So:

• बाज़ार में यह किताब sस्ती है
• लेकिन स्टेशन की दुकान में इसकी कीमत ज़्यादा है

naturally suggests higher than in the market.

If you wanted to make the comparison more explicit, you could say something like:

• बाज़ार की तुलना में स्टेशन की दुकान में इसकी कीमत ज़्यादा है।

That means:

• Compared with the market, its price is higher in the station shop.

लेकिन means but.

It connects two contrasting ideas:

• the book is cheap in one place
• but its price is higher in another place

Other common Hindi words for but include:

• मगर
• पर (very common in speech)
• किन्तु (more formal/literary)

So these are similar:

• ..., लेकिन ...
• ..., मगर ...
• ..., पर ...

In everyday Hindi, लेकिन and पर are especially common.

Not completely. Hindi word order is flexible, but the given order is very natural.

The sentence is:

• बाज़ार में यह किताब सस्ती है, लेकिन स्टेशन की दुकान में इसकी कीमत ज़्यादा है।

A common Hindi pattern is:

• [location] + [topic] + [description]

So this feels natural because each clause starts with the place being discussed.

You could rearrange parts a little, but some versions sound better than others. For learners, the given word order is a good model.

Because each clause has its own location.

Clause 1:

• बाज़ार में = in the market

Clause 2:

• स्टेशन की दुकान में = in the station shop

Hindi often makes these contrasts very clear by stating both places explicitly. This avoids ambiguity and makes the comparison easy to follow.

If the second location were omitted, the meaning would be unclear.

In careful or formal Hindi, यह is written as यह and traditionally pronounced something like yah.

In everyday speech, many speakers often say ये for singular this, especially in conversation.

So you may hear:

• यह किताब in careful/formal style
• ये किताब in casual speech

But in standard writing, यह is correct for singular this.

That said, don’t be surprised if spoken Hindi sounds a bit different from the textbook form.

Yes, absolutely.

These are both correct:

• इसकी कीमत ज़्यादा है
• इस किताब की कीमत ज़्यादा है

The difference is mainly style:

• इसकी कीमत = shorter, smoother, more natural when the book has just been mentioned
• इस किताब की कीमत = more explicit

Since किताब already appears in the first clause, using इसकी avoids unnecessary repetition.

It is basically:

• [Place 1] में + [this book] + [cheap] + है
• लेकिन
• [Place 2] में + [its price] + [higher] + है

So, piece by piece:

• बाज़ार में = in the market
• यह किताब = this book
• सस्ती है = is cheap
• लेकिन = but
• स्टेशन की दुकान में = in the station shop
• इसकी कीमत = its price
• ज़्यादा है = is higher / is more

This is a very typical Hindi sentence pattern: location first, then the thing being talked about, then the description.
