Tags: brain teaser See more , See less 8 Answer Add Tags Answer Interview Answer 8 Answers ▲ 1 ▼ .3167 - Just memorize it, it's very common. Interview Candidate on May 15, 2009 ▲ 6 ▼ I think you mean the sqrt of 0.1, not 0.01. The sqrt of 0.01 is 0.1. Scott on May 19, 2009 ▲ 0 ▼ Not to be a fuddy-duddy, but .3162 would be closer. (If you're going to take it to 4 decimals then you should use the closest 4th decimal.) rhmayer on Jun 20, 2009 ▲ 4 ▼ Answer: 0.1 assuming my 2 SCI calculators and my manual calculations are correctComments:1- 0.3167 is the square-root of 0.1 not 0.012- Don't tell you interviewer he is wrong. You want the job don't you?3- You actually need to use a 5/4 round-off using the 5th place for a more accurate 4th ( I think that's what you meant to say) Alanjai on Jul 25, 2009 ▲ 2 ▼ 0.01 is the same as 1/100 and if you take the square root of the top and bottom, you get 1/10 or 0.1. Grace on Jan 18, 2010 ▲ 7 ▼ The square root of 0.01 is neither 0.1 nor 0.3162. The square root of 0.01 is +0.1 AND -0.1 (Negative 0.1). The negative root is frequently overlooked. Robert on Jan 18, 2010 ▲ 0 ▼ Isn't it prime already? So its sq rt is 0.01. I'm so confused! Robin Richardson on Jan 30, 2010 ▲ 1 ▼ actually, square roots are always positive. the definition of a square root is that it's an absolute value.i.e. sqrt of (-1)*(-1) = |-1| = 1My real response to this topic though is that I dread such silliness in interviews. In my current position I was asked a stupid question in a 5-on-1 interview and basically said what I thought about the question but still got the job - so maybe that was the correct answer. Hope I don't ever find myself desperately needing a job and having to endure this silliness again. bob on Feb 3, 2010 Interviews > Trader > Morgan Stanley Add Answers or Comments To comment on this, Sign In or Sign Up.
