A question paper from the Indian Institute of Technology, Kanpur (IIT-K) has been circulating on social media. One of the questions, shared on ‘X’, features examples involving Arvind Kejriwal and Prime Minister Narendra Modi.

Question:

After a crushing defeat in the Delhi elections, IIT Alumnus Mr. Arvind Kejriwal wants to tune into the “Mann ki Baat” program by our Prime Minister on the Vividh Bharti (AIR) FM at a frequency of 105.4 MHz. Mr. Kejriwal wants to design a filter which may pass the content of Vividh Bharti channel while attenuating (rejecting) the adjacent FM radio channels Radio Nasha (107.2 MHz) and FM Rainbow Lucknow (100.7 MHz) by at least -60 dB. Since he spent a lot of money during the election campaign, he can only afford a resistor of 50 £2, a variable inductor and a variable capacitor to design this filter. Can you please help Mr. Kejriwal design this filter using the R, L, and C components and find out:

(a) the quality factor (2) of this filter.

(b) the values of inductance and capacitance needed.

IIT Kanpur has confirmed to News18.com that the circulating image of the question paper is authentic.

Speaking to News18.com, an official from IIT Kanpur clarified, “While the authenticity of the image was questioned, we can confirm that it is a real question paper, drafted by one of our professors for a small, internal class quiz.”

“The faculty member in question often uses references to well-known personalities—both real and fictional—to make exam questions more engaging for students. In the past, similar references have included characters like Tony Stark. The intent behind this approach is purely academic, with no other implications,” the official added.
