This is not on the GMAT. Do not waste your time memorizing SD percentiles. Stop using whatever prep material is telling you to do that.

Better still, there is no answer to this question as stated, because it doesn't say there is a normal distribution.

Thanks Greg.

It wasn't a question given in some study material.
I came across this question, but wasn't able to solve, so asked.
