    but i have a confusion. in the question it was mentioned that a standing wave was forming..

    but for a standing wave to form there must be two notes at the ends... but here anti-nodes are forming.
    so standing wave is not produced.. so .??

    It isn't a must that there should be nodes at the ends. There can be antinodes

    Everyone doesn't have the same uncertainty, it's 1 mm if you chose metre rule in the previous answer. For those that chose a different answer their uncertainties should be different, for example 0.3% if vernier scale used.

    Btw, I write my answer as 3.33% instead of 3 or 3.3%... is it alright to write with answer 2 d.p?
