Image result for standard deviation formula 

is the formula of standard deviation. it is clear that the standard deviation is independent of the constant since the mean and the value of x alredy depend on the constant.

therefore the standard deviation will remain the same.

please do some correction,

we have the new standard deviation as S2/S1=93

but S1=95

S2/95=93

S2=93*95

S2=8835 which is the new standard deviation
