Number of data values : n= 6
The mean value of the given data will be :-

The formula to find standard deviation:_
![\sqrt{\dfrac{\sum(x-\overline{x})^2}{n}]](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cdfrac%7B%5Csum%28x-%5Coverline%7Bx%7D%29%5E2%7D%7Bn%7D%5D)
Now,

The standard deviation will be :-

The equation you want to use is this:
10x = 530 10 pages for x days
x = 530/10 530 pages divided by 10 pages
So the answer is,
