Could you tell me a laptop with Windows 10 and Intel Core i3 processor under 20000 rupees in India?

Finding a laptop with 15.6 inch display, i3 processor and Windows 10 operating system under 20000 is not at all possible. Instead of that,  we suggest our customers the Pentium N3540 or Celeron N3050 processor with Linux operating system. These processors are good and the Pentium N3540 is much suitable for all your day to day computer work. Most of the Core i3 Laptops are available only  between 30000 and under 35000 price range.

Which brand have good laptops with Pentium processor below 20000 rupees?

Dell, Acer, ASUS, HP and Lenovo all are having models with 15.6 inch display and Pentium processor. But all of them are without Windows 10 operating system.

Which Linux distro you recommend for a laptop with Pentium or Celeron processor?

The UBUNTU Linux is a good distribution. However we recommend the Linux Mint and the LUBUNTU for a laptop with less processing power. We use old system with LUBUNTU to do most of the web designing works without any single issue for the last 2 years. You could also dual boot Linux with Windows 10.
