How tax is calculate on Capital Gains Income

Hello!

I'am new to this forum i have some questions please clear my doubts

I have viewed this example https://cleartax.in/s/capital-gains-income

If we brought any item 5 lakhs and we sold  for 10 lakhs and for example fees is 1 lakh( fees is not correct but taken as example)

and it is less then 3 years and how it is calculated....? i mean how much tax we should pay.....?

How much percentage we should pay like 10% or 15%.

When Tax is applicable on capital gains i mean for example like above 4 lakhs or 3 lakhs or .....?

Thanks!
