Question Nos. 59 and 70 in Official Quant Guide

[Nauman]

Can anybody explain the difference of logic behind in Question Nos. 59 and 70 in the Official Quant Guide?

Q 59 asks for the value of "exactly 2 standard deviation less than mean" and calculates it as: " [mean - 2 standard devistion]", while Q 70 asks for "value more than 2.5 standard deviation from the mean" and calculates it as in the range: "[mean - 2.5 standard devistion] and [mean + 2.5 standard devistion]. Why the range in Q 70 not in Q 59?

On the number line, "Less" means number on the left (only 1 direction); whereas away is more like the |x| (absolute operator) which means on wither sides.
Hope this answers your question.
