some maths questions:

1. Mean was given for exact no.of observations. Then one obsevation was wrong which was given nd its actual value was also given . Find actual mean.
Like mean of 5 observations is 10. One observation was reported wrong as 32 instead of 25. Find new mean

2. Around 6-7 diff numbers were given
Find mean deviation about mean

3. Which is not a logical statement?
don't remember options
