It said ' Ratio ___________________'
I double checked.
And we had to write the RATIO correct to sig fig which was 36:23.

No, they said that the REFRACTIVE INDEX can be calculated with the RATIO GIVEN.
We had to input the measurements and get the value for refractive index.

Refractive index is not a RATIO, it's a value.

You don't write refractive index as X:Z... Furthermore, in the past papers, whenever it says "to appropriate number of significant figures", the answer is always a decimal number.

Question 1 part b. How to measure Length L correctly.

I said immerse the rule into the water as zero mark co-incides with the water level.
And then align it vertically with rod, and use set-square to find the answer. I also drew all this apparatus on the figure.

EVERYONE HAS A DIFFERENT WAY.

Someone is using a cobalt chloride paper.
Someone is pulling out the rod, and marking the water prints.
Someone is marking the beaker.
Someone is inserting the rule on the side.

Is my answer right?
