The next part gathers the numbers after "D" (minus the date) and formats them into a 5-digit text string (some existing standards have 5-digit numbers in them, so this is designed to handle them as well). Since we only want one letter, we can use "1" for num_chars, so here is the part that grabs the "D": By finding the space (" ") in cell A2, and adding 1, we get a number representing the first character after the space in our string: The FIND command is used to extract the start_num of the string we want. The text part of the formula indicates the cell being read, which is in this case A2. For ASTM D6615-2010, we want to isolate the "D." The MID command is used to extract information from the middle of the string. =CONCATENATE(MID(A2,FIND(" ",A2,2)+1,1),TEXT(MID(A2,7,FIND("-",A2)-7),"00000"))įirst we want to find the letter of the string we want to use to sort and isolate it from the numbers. Here is the formula we used if the first item to sort was in cell A2: I am going to grab the string in the middle of the standard number and format it so the string is the same length for all standards, and then sort by that string instead of the one shown above. Notice how the numbers in the thousands are placed before the numbers in the hundreds in a standard Excel sort. To understand how this works, here is a sample from a recent list of records we tried to sort in Excel: ASTM D6615-2010 When it was printed for users, the standards were in the order they would be in the file. I used this to sort a file of ASTM standards that had changes from what we had in print. The following formula will grab text and numbers from a string and concatenate them into a sortable string. Any alpha numeric sort places the alpha in order, and then numbers in order by their first numeral, so 1300 will come before 140 which does not work well for lists like call numbers in libraries. Q6.This formula uses CONCATENATE(), TEXT(), MID(), and FIND()Ī frustration while sorting in Excel is an alpha-numeric string of characters, like a call number or standard number. Therefore option c is the correct answer.ĭirection (6-10): Study the following digit-letter-symbol sequence carefully and answer the questions given below. How many letters are there which are preceded by a symbol and followed by a number within the group in the given arrangement? Therefore, option d is the correct answer. So, fourth from the left end and eleventh from the right end – D and 6 If the numbers which are preceded by letters interchanged their positions and those letters were changed to the next letter in the alphabetical series, then which of the following elements are the fourth from the left end and the eleventh from the right end?Īfter operation – B 7 C N R % 5 $ 6 G K M & 4 S # P 5 UĪfter changing – B 7 D N R % 5 $ 6 H K M & 4 S # P 5 V Which of the following is second to the left of the twelfth from the right end if all the symbols are dropped?Īfter dropping symbols – B C 7 N R 5 G 6 K M 4 S P U 5 Based on the given arrangement which of the following groups should be next?
