JEE Main 2020 Sample Question Paper With Solution For Numerical Value

The National Testing Agency (NTA) was vested with the authority to conduct the JEE Main exam. The Joint Entrance Examination (JEE) Main exam will be held twice a year in January and April. NTA has released the sample questions for the Numerical Value section, which will be conducted for the first time. The Agency has released the sample questions in numerical value - physics and chemistry. Aspirants who are aiming for the JEE Main in 2020 can access the sample question paper with the solution on the official website - jeemain.nta.nic.in.
