Interview Q&A / Aptitude

1. How do you quickly approximate a value like '3,487 is what percent of 15,012?' in a timed data interpretation section?

   Round both numbers to friendly values close to the originals: 3,500 / 15,000 = 7/30, about 23.3%. The exact value is 23.23%, so the estimate is enough to pick the right option when choices are reasonably far apart.
