The question was shared on the Twitter handle @ias_keeda with the caption, “Solve this CSAT question of UPSC CSE pre 2023 #UPSC.” The aptitude question challenges candidates to determine the remainder when multiplying a specified set of numbers by 100.

Are you smart enough to solve the below question?

Since being shared on June 3, the tweet has been viewed over 54,300 times and received more than 500 likes. It has also accumulated a flurry of comments from netizens. While many wrote “0” or “Zero” in the comments, others typed out the solution.

Check out a few reactions here:

“(a) 0. 85 and 95 are divisible by 5. So, 100 is divisible by 25 so the denominator becomes 4. 4 completely divides 96. So, the remainder is 0,” posted an individual. Another added, “I solved it correctly in the exam. Just multiplied the last digit of all the numbers and got 0 which if divided by 100 will give 0 - a simple one I guess.” “85x87x89x91x95x96÷100=5462159976 reminder=0,” wrote a third. A fourth commented, “The correct answer is O only.”
