In how many districts of Bihar does the headquarters have the same name as the district?

Correct answers: (a) 30 or (c) 29

Explanation

Bihar has 38 districts. In most, the headquarters has the same name as the district. In these it does not:

• Rohtas (Sasaram), Kaimur (Bhabua), Bhojpur (Arrah), Nalanda (Bihar Sharif);
• Saran (Chhapra), West Champaran (Bettiah), East Champaran (Motihari), Vaishali (Hajipur).

That leaves 30. The book counts 29, because it takes the headquarters of Sitamarhi as Dumra.

The book's key is (c), 29, which takes Dumra as the headquarters of Sitamarhi district. Sitamarhi's headquarters is usually given as Sitamarhi, which makes 30, so (a) is also accepted.
