I'll assume this is simple interest
+I+=+P%2Ar%2At+
+I+=+6200+-+4000+
+I+=+2200+
-----------------------
+2200+=+4000%2Ar%2A10+
+r+=+2200%2F40000+
+r+=+22%2F400+
+r+=+11%2F200+
+r+=+.055+
+.055%2A100+=+5.5+
Annual rate = 5.5%

To get a correct answer, you need to be much, much clearer.
For one, are you saying that the investment was made in year 6 and went into year 10? If so, that's a time of 4 (10 - 6) years.
Furthermore, what's the ANNUAL compounding period?
