In one of the assignments that I was solving at 06:00 IST, I ended up with the equation:
3.65 – x + 0.5 = 1.5
Therefore, x = 2.65.
I turned to my roommate, who was also solving the same assignment at 06:00 IST, and asked him what his answer was. He merrily answered, “x = 3.65.” Crash!!!!! “How man, how?” I asked. His reply:
(3.65 – x) * 20,000 + 0.5 * 20,000 = 30,000
(3.65 – x) * 20,000 = 20,000
3.65 – x = 0
Therefore, x = 3.65.
For a minute I was convinced by his argument. I re-checked my calculations, but could not find a thing wrong. He re-checked his calculations, but could not find a thing wrong. Amazing! A feeling of serendipity began to fill the air. Had we discovered a loophole in Mathematics? Would we win the next Nobel Prize in Mathematics?
Imagine our dismay when we figured out what was happening!
Moral of the story: Don’t listen to your roommate at 06:00 IST.
