Need Laptop for College under 45k-50k inr

Budget: (₹45,000)
Country: (India)
Use Case: (Gaming - No, for college use i.e notes, pdf, coding, daily use)
Preferred Specs: (whichever best I can get, i have absolutely no idea about specs)
Notes: (i want the laptop to last for 4-5 years, should run smoothly even in 3rd year of purchase, strong performance, no hang in b/w and stuff. I am going to get core branch in T1 clg (mech,civil,chem engg), so I will have to code along with my main coursework, hence laptop should handle decent or moderate codes and coding programmes. Thanks! )
