(Left) 6 N % 4 & H 7 @ 3 S 6 # G F ! 5 R 3 * D $ (Right) How many such symbols are there, which are immediately preceded by a letter and also immediately followed by a number?

Each of the digits in the number 5274381 is arranged in ascending order from left to right. The position of how many digits will remain unchanged as compared to that in the original number?

Each of the digits in the number 6743219 is arranged in ascending order from left to right. What will be the sum of the digits which are second from the left and second from the right in the new number thus formed?

Each of the digits in the number 8539264 is arranged in descending order from left to right. The position(s) of how many digits will remain unchanged as compared to that in the original number?

This question is based on the five, three-digit numbers given below. (Left) 654 842 684 714 385 (Right) (Example- 697 – First digit = 6, second digit = 9 and third digit = 7) NOTE - All operations to be done from left to right. If all the numbers are arranged in ascending order, the position of how many numbers will remain unchanged?

In the following number sequence, how many times an odd number is immediately followed by an even number?

5 3 8 4 7 9 6 5 3 9 2 7 8 2 1 4 5 6 3 8 2 6 5 8 6 7

Select the set in which the numbers are related in the same way as are the numbers of the given sets.

( NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits.

E.g. 13 - Operations on 13 such as adding /subtracting /multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)
