The answer is "0200". Did you get it right?

6 Figure References

A six figure reference is used to pinpoint a specific point within a square. Numbers 1,2,4 and 5 are the 4 figure reference. Numbers 3 and 6 are the position of the point within the square, in tenths.

Example:

 03 02 + 01 Z 00 01 02 03

Point + is directly in the centre of square "0101". It is therefore 5/10 from each side. So, the six figure reference is:

015 015

The bottom left hand corner of square Z would be described as 010 000 - remember, it still needs a six fig reference.

BUT THAT'S NOT ALL YOU NEED TO KNOW

These figures are repeated every 100km, so you need to be able to identify where in the country you are. One way is to use the letter system (for example, most of the Leicestershire area is on sheet SK. This sheet is also known as 4,3. So, a point on this map could be described with an 8 figure reference:

The church at Oaks in Charnwood, can be described as:

4473 3163

The sheet is 4,3. The square is 4716 and the point is 3,3. This means that the point is 447.3km east and 316.3km north of the start of the mapping system.

Further figures can be added to the end, to be more precise. However, using ordinary scale maps, this is as far as you are likely to need to go
