Step 1: Ignore last three digits of 21952. Remaining number left is ’21′.
Step 2: From the above table cube of ’2′ is less than ’21′. Therefore left part (L) of our answer will be ’2′.
Step 3: Since last digit of ‘21952‘ is ‘2‘. Therefore right part (R) of our answer will be ’8′. (Because Last digit of ‘cube of 8′ is 2. see table above.)
Step 4: Our Answer will be L|R. Therefore Answer will be 2|8 = 28.
This is a very good trick.
Hope This Helps.
