Here, we have to look for vowel-symbol-number arrangement :R J 3 D # T M 9 % P E $ K 2 H A * N 5 I * 4 6 U 7 β I V 8 F

Here, we have to look for symbol-consonant arrangement :R J 3 D # T M 9 % P E $ K 2 H A * N 5 I * 4 6 U 7 β I V 8 F

R J 3 D # T M 9 % P E $ K 2 H A * N 5 I * 4 6 U 7 β I V 8 F8th to the left of the 20th from the left = 20 - 8 = 12th from the left, i.e.,  $

Here, we have to look for consonant-number-consonant arrangement :R J 3 D # T M 9 % P E $ K 2 H A * N 5 I * 4 6 U 7 β I V 8 F

Here given number is 95137248. When the number is arranged in ascending order number becomes as follows 12345789. Now look at the following pairs 35, 38 and 47. What you observe? These pairs are those pairs each of which has as many digits between them in the number as when they are ascending order.

After interchanging the number becomes as follows :8 0 1 6 4 3 5 9 7 2Hence, the fourth digit from the right end is 5.

Here the given numbers are :517   325   639    841    792
After reversing, the numbers become as follows715   523   936   148   297When arranged in descending order the numbers become as follows:936   715   523   297   148Now, the third number from top is 523. Hence, the last digit of 523 is 3.

Fifth element towards right of the seventeenth element from the right end implies twelfth element from the right end. Hence, the required element is 4.
