Okay, $30000 (INR) is roughly equivalent to $461.32 (USD; rounded up to the nearest cent) as of Friday October 23, 2015 (16:10, PDT). There's absolutely no way you can buy a new Macbook, Macbook Air, or Macbook Pro.
Here's a listing of what Apple has to offer "at base" and retail:
■ The cheapest (new) Macbook is $1,299.00 (USD)
■ The cheapest (new) Macbook Air is $899.00 (USD)
■ The cheapest (new) Macbook Pro is $1,099.00 (USD)
With education pricing, the laptops sell for a bit less.
■ The cheapest (new) Macbook is $1,249.00 (USD)
■ The cheapest (new) Macbook Air is $849.00 (USD)
■ The cheapest (new) Macbook Pro is $999.00 (USD)
Clearly, none of the above are even remotely in your range. So, let's see if there's anything that's refurbished that does meet the marker.
■ "Refurbished 11.6-inch MacBook Air 1.6GHz Dual-core Intel Core i5" goes for $759.00 (USD)
■ "Refurbished 13.3-inch MacBook Pro 2.5GHz Dual-core Intel i5" goes for $829.00 (USD)
Nope, nothing is in your range. Your best bet at finding a Macbook/Macbook Air/Macbook Pro is second-hand used. Sorry, dude/dudette.
