Harish Kaushik, a user, said if investors start asking similar questions from fund managers in Mutual Fund houses, the streets will be cleaner.
Sarvesh M Soman, another user, called it a brilliant way of seeking out experts. "Hope maths guys solve it," he said.
Another user said he was thinking about the number of wrong phone numbers dialed in by aspirants, referring to those who might not get the equation right and dial the wrong person.
One person advised - just to paste the equation on ChatGPT and get an answer. However, another user that it was a nonsense advertisement. "This equation can be asked of in the interview of relevance. If the candidate isn't able to solve, it doesn't at all mean that the candidate is unfit," the user said.
