Badrinath ki Dulhania: Alia Bhatt makes Varun Dhawan solve math sums for promotions

Badrinath Ki Dulhania is on a pre-release promotional drive. Vaidehi (Alia Bhatt) asks Badri (Varun Dhawan) to solve some math calculations. The calculations are rather easy: 12-5, then add three and then subtract two. Varun stumbles a bit, but gets the answer right. The catch is, the answer is the number of days left for the release of Badrinath ki Dulhaniya - eight.

Bollywood actors Alia Bhatt and Varun Dhawan are painting the town red with their promotional antics for their upcoming film, Badrinath ki Dulhania.

Alia Bhatt and Varun Dhawan will be seen together in Badrinath ki Dulhania.

Alia Bhatt and Varun Dhawan made their Bollywood debut with Student of the Year.

Alia and Varun have shared a video on their Instagram that shows Vaidehi (Alia) asking Badri (Varun) to solve some math calculations. The calculations are rather easy: Subtract 5 from 12, add three and then subtract two. Varun stumbles a bit, but gets the answer right.

The catch is, the answer is the number days left for the release of Badrinath ki Dulhaniya - eight.

Badrinath Ki Dulhania is a spin-off of its prequel Humpty Sharma Ki Dulhania, which released in 2014. The film, which reprises its star cast, marks the third film of Alia and Varun together. They made their Bollywood debut with Student of the Year (2012).
