Question 31. Use the following series of elements (alpha-number-symbol) to answer these questions. Every two-digit number (given in brackets) is to be treated as single number.2 * 8 56 B 9 $ Q 3 E 1 7 R D 4 £ (13) U . K (18) A (14) PIf each alphabet has a value of zero, each symbol has value equivalent to the square of the numeral that immediately precedes the symbol or the value of 1 if it is not immediately preceded by a numeral, what will be the sum of the values of the first 10 elements of the series starting from the left end?

Answer: Option A. -> 118


2 + 22 + 8 + 5 + 6 + 0 + 9 + 92 + 0 + 3 = 118Where value of alphabet = 0; symbol = square of the previous number; number = the value itself.


Question 32. Study the following number series to answer these questions.2 6 7 5 4 3 7 4 8 9 3 2 5 4 7 9 8 6 8 7 1 2 5 3 7 6 8 9 3 6In a certain code language the word 'NUMBER' is written as 'UMHTEL'. How will the word 'SECOND' be written in that language?

Answer: Option B. -> GRQDRB


If we number the letter of the word from 1 to 6, first rearrange the letters in the order 615243. Next, to this reversed order of letters, apply the following alternately: move three letters ahead; go one letter backward.Thus NUMBER first becomes RNEUBM. Then R + 3 = U, N - 1 = M, E + 3 = H, U - 1 = T, B = # = E, M - 1 = L. So the final code is UMHTEL.Similarly, SECOND -> DSNEOC -> GRQDRB


Question 33. Study the following number series to answer these questions.2 6 7 5 4 3 7 4 8 9 3 2 5 4 7 9 8 6 8 7 1 2 5 3 7 6 8 9 3 6The following numbers are rewritten by interchanging the digits in ten's place and hundred;s place and then arranged in the descending order. What will be the second digit of the newly formed fourth number from the top?478    736    895    978    389    675

Answer: Option E. -> 6


Interchanging, we get 749, 376, 985, 798, 839, 765. Rearranged in descending order, this becomes 985, 839, 798, 765, 749, 376.


Question 34. Use the following series of elements (alpha-number-symbol) to answer these questions. Every two-digit number (given in brackets) is to be treated as single number.2 * 8 56 B 9 $ Q 3 E 1 7 R D 4 £ (13) U . K (18) A (14) PFour of the following five groups of elements are alike in a certain way and so form a group. Which is the one that does not belong to that group?

Answer: Option D. -> 1 3 E


Other groups consist of consecutive elements.

Answer: Option D. -> $


= (19 - 7) = 12th from the right end.


Question 37. Answer these questions referring to the symbols-letter-number sequence given below:E G 4 B H 7 5 @ K 8 D N £ Q Z $ W 3 C 1 9 * L B 2 S 6Which of the following is exactly in the midway between the ninth from left end and the seventh from the right end?

 Discuss Question
Answer: Option B. -> Z


There are 27 elements in all in the sequence.SO, (27 - 9 - 7) = 11 elements are between the 9th from left and 7th from right.Hence, (9 + 6) = 15th element from the left end will be the required answer.


Question 38. Answer these questions referring to the symbols-letter-number sequence given below:E G 4 B H 7 5 @ K 8 D N £ Q Z $ W 3 C 1 9 * L B 2 S 6If the first fifteen elements are written in the reverse order then which of the following will be seventh to the left of twelfth element from right end?
  1.    7
  2.    @
  3.    5
  4.    K
  5.    None of these
 Discuss Question
Answer: Option C. -> 5


7th to the left of 12th from right = (12 + 7) = 19th from right= (27 - 19 + 1) = 9th from leftBut the first 15 elements are reversed.So, 9th from left in this reversed sequence = (15 - 9 + 1) = 7th from left in the original sequence = 5.


Question 39. Answer these questions referring to the symbols-letter-number sequence given below:E G 4 B H 7 5 @ K 8 D N £ Q Z $ W 3 C 1 9 * L B 2 S 6How many such digits are there in the above sequence which are immediately preceded as well as followed by digits?
  1.    None
  2.    One
  3.    Two
  4.    Three
  5.    None of these

Answer: Option A. -> None


For the condition to be fulfilled, three digits should be together but it is not so in the given sequence.


Question 40. In a class of 60, where girls are twice that of boys, Kamal ranked seventeenth from the top. If there are 9 girls ahead of Kamal, how many boys are after him in rank ?
  1.    3
  2.    7
  3.    12
  4.    23
  5.    32
 Discuss Question
Answer: Option C. -> 12


Let the number of boys be x. Then, number of girls = 2x.     x + 2x = 60 or 3x = 60 or x = 20.So, number of boys = 20 and number of girls = 40.Number of students behind Kamal in rank = (60 - 17) = 43.Number of girls ahead of Kamal in rank = 9.Number of girls behind kamal in rank = 40 - 9 = 31.Number of boys behind Kamal in rank = 43 - 31 = 12.
