Yes. But in approximation we have to use Standard Deviation so we needed to add SquareRoot to thay 32. And I forgot that. :/

720 is correct.
240 is wrong, Its 80.
And 49 is wrong. As it was less than 1000? So you only did that with three digit number right? There were also 2 digit numbers ( less than 100) and also one digit number ( 5 ) So Answer was nearly 49+7 I guess = 56.
