The promo shows Amitabh Bachchan asking Gurudev how did he manage to become an HOD (head of department) in a subject like maths, which is so difficult. The contestant explained to the veteran actor that maths is a ‘one time investment’ as whatever he would have learnt in class 2-3, he would still be having that knowledge, while he would have not remembered what he learnt in the subject of history or Sanskrit. Amitabh listened to him carefully and almost in awe and said, “Ab samajh mein aaya aapke mata pita ne aapka naam Gurudev (teacher) kyu rakha hai (Now I understood why your parents named you Gurudev).”

Amitabh is seen asking him a question for ₹12 lakh and when Gurudev choses option B, the actor gestures at something, as if hinting at what next. After several attempts, Amitabh finally tells him that he needs to say it out loud that he wants to lock the option, in order to finalise his answer.

Sony shared the promo for the Friday episode with the caption, “Maths mein nipunta haasil karne waale Gurudev ji apne gyan se jeet paayenge kitni dhanrashi? (How much money will the math champion Gurudev win on the show)?”

In the last episode, Amitabh was shocked to see a contestant who celebrated his win by removing his shirt and asking audience to continue to clap for him. He roamed around the stage in a vest after making it to the hot seat. He finally took home ₹10,000.
