Significant Figure Question CIE Physics watch

1. Teachers have instructed me to give answers in the lowest significant figure. In most of the questions it works out well, but some answers to questions in the marking scheme don't have that followed.
Example from a marking scheme:

Spring Constant= 6.4/0.12=53.3

Now this answer should have clearly been 53 because 2 is the lowest sig fig used in the equation.
I don't know how this is possible.Help needed!
And just that you know this is a 1 mark question. If the answer is wrong(not 53 exactly) , anyone loses the one mark.
2. Sorry you've not had any responses about this. Are you sure you've posted in the right place? Here's a link to our subject forum which should help get you more responses if you post there.

I mean how is the answer in the marking scheme 53.3 when it should have been just 53 if we consider the lowest sig fig rule.

which means your teacher's rule is wrong.
