ZLEPUZ:
Z+1 = A

49 – 7 $\times$ 13 + 14 = $\frac{49}{7}$ + 13 – 14 = 6

$\frac{132}{12}$ + 15 = 26
$\frac{156}{13}$ + 11 = 23

$\therefore$ $\frac{143}{11}$ + 12 = 25

25 $\times$ 5 – 25 = 100
24 $\times$ 10 – 40 = 200

$\therefore$ 36 $\times$ 7 – 52 = 200

49 + 7 – 21 = 35
29 + 8 – 14 = 23

$\therefore$ 17 + 4 – 13 = 8

$14$ $\times$ $\frac{9}{3}$ $=$ $42$
$21$ $\times$ $\frac{9}{7}$ $=$ $27$

$\therefore$ $16$ $\times$ $\frac{8}{4}$ $=$ $32$

7 + 8 $\times$ 4 = 39
15 + 3 $\times$ 9 = 42

$\therefore$ 19 + 7 $\times$ 2 = 33

14 $\times$ 7 – 68 = 30
13 $\times$ 8 – 42 = 62

$\therefore$ 9 $\times$ 6 – 14 = 54 – 14 = 40

5 + $\frac{6}{2}$ = 8
3 + $\frac{9}{3}$ = 6

$\therefore$ 4 + $\frac{12}{4}$ = 7

17 + 9 $\times$ 5 = 62
13 + 8 $\times$ 4 = 45

$\therefore$ 15 + 4 $\times$ 3 = 27

24 + $\frac{112}{7}$ = 24 + 16 = 40
57 + $\frac{216}{24}$ = 57 + 9 = 66

$\therefore$ 49 + $\frac{114}{19}$ = 49 + 6 = 55

13 M 3 N 15 P 5 L 9 = 13 – 3 $\times$ $\frac{15}{5}$ + 9 = 13

15 L 24 N 7 M 13 N 9 = 15 + 24 $\times$ 7 – 13 $\times$ 9 = 15 + 168 – 117 = 66

108 $\times$ 19 – 57 $\times$ 9 $\div$ 14 = $\Large\frac{108}{19}$ $\times$ $\Large\frac{57}{9}$ $+$ $14$ = 36 + 14 = 50

17 $\div$ 23 – 5 + 38 = 17 + 23 $\times$ 5 – 38 = 17 + 115 – 38 = 94

54 + 117 $\times$ 8 – 32 $\times$ 9 equals 54 – 117 $\div$ 9 $\times$ 32 $\div$ = 54 – 52 = 2

24 + $\frac{112}{7}$ = 24 + 16 = 40
57 + $\frac{216}{24}$ = 57 + 9 = 66

$\therefore$ 49 + $\frac{114}{19}$ = 49 + 6 = 55

39 – 4 $\times$ 3 = 27
67 – 7 $\times$ 2 = 53

$\therefore$ 27 – 5 $\times$ 4 = 27 – 20 = 7

46 + 4 $\times$ 8 = 75
36 + 3 $\times$ 9 = 63

$\therefore$ 29 + 6 $\times$ 7 = 71

322 D 46 B 473 D 43 + 392 D 28 = $\Large\frac{322}{46}$ $-$ $\Large\frac{473}{43}$ $+$ $\Large\frac{392}{28}$ $=$ $7$ $-$ $11$ $+$ $14$ $=$ $10$

56 A 648 D 9 B 48 = 56 + $\frac{648}{9}$ – 48 = 56 + 72 – 48 = 80

301 D 7 A 288 D 8 C 36 D 16 = $\frac{301}{7}$ $+$ $\frac{288}{8}$ $\times$ $\frac{36}{16}$ $=$ $43$ $+$ $81$ $=$ $124$

45 $\times$ 6 $\div$ 27 = 10
148 $\times$ 2 $\div$ 37 = 8

$\therefore$ 96 $\times$ 3 $\div$ 16 = 18

56 – 5 $\times$ 11 = 1
23 $\times$ 3 – 14 = 55

$\therefore$ 47 – 14 $\times$3 = 47 – 42 = 5

459 $\div$ 9 + 3 = 54
161 $\div$ 7 + 5 = 28

$\therefore$ 192 $6 @ 7 = 192$\div$6 + 7 = 39 26) Answer (A) + —–$\times$– —— +$\times$——-$\div\div$—— – Then, 567$\times$9$\times$21 – 15 + 3$\div$4 equals 3 + 15$\times$3 – 4 = 44 27) Answer (C) + —–$\times$– —— +$\times$——-$\div\div$—— – Then, 220$\times$4$\div$11 + 2 – 167 equals 220$\div$4 -11$\times$2 + 167 = 55 – 22 + 167 = 200 28) Answer (B) + —–$\times$– —— +$\times$——-$\div\div$—— – Then, 150 – 5$\times$6 + 36$\div$8 equals 150 + 5$\div$6$\times$36 – 8 = 150 + 30 – 8 = 172 29) Answer (C) 30) Answer (B) The positions of alphabets in the given word are reversed. Hence, the code for NATIONAL will be LANOITAN Hence, option B is the correct answer. 31) Answer (C) The pattern followed here is, E + 2 = G ; A + 2 = C ; R + 2 = T ; N + 2 = P i.e (n + 2) NEAR is coded as, N + 2 = P ; E + 2 = G ; A + 2 = C ; R + 2 = T NEAR – PGCT Hence, option C is the correct answer. 32) Answer (D) In the given code language, alphabets are directly related to the numbers on the right. D = 5 ; I = 4 ; C = 7 ; T = 9 ; O = 8 ; N = 2 ; A = 3 ; R = 6 ; Y = 1. Hence, code for YARD is ‘1365’ Hence, option D is the correct answer. 33) Answer (B) SUNDAY is coded as ‘012345’ and BIG is coded as ‘678’ Each alphabet on the left is directly related to each number on the right. S = 0 ; U = 1 ; N = 2 ; D = 3 ; A = 4 ; Y = 5 ; B = 6 ; I = 7 ; G = 8 In the same way, SANDBAY is coded as ‘0423645’ Hence, option B is the correct answer. 34) Answer (A) 35) Answer (A) 36) Answer (C) The sum of the numbers corresponding to the respective alphabets. BALL ;$2+1+12+12=27$CANE ;$3+1+14+5=23$YELL ;$25+5+12+12=54\$

=> Ans – (C)

“GRAVYS” is written as “DUJVBY”

The numbers are shifted by a factor of +3 in the following pattern.

“BUTLTS” is written as “WXEVWO”

=> Ans – (D)

“BANGED” is written as “JJKQCC”

“TILTS” is written as “XXOKU”

Similarly,

STRAY : DEUVT

=> Ans – (D)

The pattern followed is :

CAB = 3 + 1 + 2 = 6

LEG = 12 + 5 + 7 = 24 = 2 + 4 = 6

MAP = 13 + 1 + 16 = 30 = 3 + 0 = 3

=> Ans – (C)
