Tripathi was sworn in by Gauhati High Court Judge Justice Miachael Zothankhuma. The swearing in ceremony was attended by Chief Minister Lal Thanhawla, his cabinet colleagues, legislators and senior government officials.
Tripathi was appointed to take additional charge of Mizoram after state governor Aziz Qureshi was sacked by the Centre on March 28.
Earlier, Tripathi was accorded customary official reception at the Lengpui Airport where the state police gave him a guard of honour.
He was received at the airport by Lal Thanhawla, state home minister R Lalzirliana, chief secretary Lalmalsawma and DGP Dharmendra Kumar.
Meanwhile, the Mizo Zirlai Pawl (MZP) or the students federation staged a protest in front of the Raj Bhavan and raised slogans condemning what they termed as 'the Centre using Mizoram as the gubernatorial dumping ground'.
The students also announced their intention to gherao central government offices on Tuesday and again stage a protest during President Pranab Mukherjee's visit on April 9 and 10.
