Coding-Decoding

 In a certain code SPRING is written as TRUMSM. How will ANGLES is written in that code language? A) BPHFMT B) BPJPJY C) YQHJPB D) TMFHPB Correct Answer : BPJPJY Explanation :The pattern is ST (1) PQR (2) RSTU (3) IJKLM (4) NOPQRS (5) GHIJKLM (6) Hence, AB NOP GHIJ LMNOP EFGHIJ STUVWXY If RACKET is written as 813524 in a certain code, how would TRACK be written? A) 24813 B) 35418 C) 48135 D) 54312 Correct Answer : 48135 Explanation :RACKET 813524 therefore T = 4 R = 8 A = 1 C = 3 K = 5 In a certain code BREAKER is written as DPGBMCT. How is MOTHERS written in that code language? A) OMVIGPU B) UPGIVLO C) SRETHOM D) OMVIUPG Correct Answer : OMVIGPU Explanation :The given pattern is as follows: B -> C -> D R <- Q <- P E -> F -> G A -> B K -> L -> M E <- D <- C R -> S -> T That is why mothers is written as M -> N -> O O <- N <- M T -> U -> V H -> I E -> F -> G R <- Q <- P S -> T -> U Therefore, the code will be OMVIGPU. In certain code language ‘nu ku pu’ mean ‘who are you’, ‘ku lu tu du’ means ‘you may come here’.What does ‘nu’ means in that code language? A) how B) who C) wee D) who or are Correct Answer : who or are Explanation :‘nu ku pu’ = ‘who are you’ ----eq1 'ku lu tu du’ = ‘you may come here’ ----eq2 from eq1 and 2 the common word is 'ku'=you so, from eq1 'nu' = who or are If A = 1, B = 3, C = 5 and so on. In the same language, value of ON is 56. Which of the following is the numeral value of the word URGENT? A) 124 B) 164 C) 150 D) 220 Correct Answer : 164 Explanation :A = 1, B = 3, C = 5, D = 7, E = 9 .........N = 27, O = 29, P = 31 ..... ON= O + N = 29+27 =56 So, URGENT =U+R+G+E+N+T=41+35+13+9+27+39 =164 In a certain code, SEND is written as 2%*@ and DREAM is written as @ \$%#5. How is MADE written in that code? A) 5#@% B) @\$%5 C) 5%#@ D) 2@%\$ Correct Answer : 5#@% Explanation :SEND = 2%*@ -----(i) DREAM = @ \$%#5 -----(ii) from eq (i) and (ii) , D=@ ,E=% ,A=# ,M=S Therefore, MADE => 5#@% In a certain code language, MONDAY is coded as OQPFCA. How can ENERGY be coded as? A) GPGTIA B) FPFTIA C) GOGTJA D) GPGSHZ Correct Answer : GPGTIA Explanation :M>+1>O O>+1>Q N>+1>P D>+1>F A>+1>C Y>+1>A Therefore, ENERGY > GPGTIA In a certain code language, GATE is written as 3*4@ and ROAD is written as \$2*5. How will DEAR be written in the same code? A) 54*\$ B) 5*@\$ C) 5@*\$ D) \$*@5 Correct Answer : 5@*\$ Explanation :As is given, GATE = 3*4@ ---eq(i) ROAD = \$2*5 ---eq(ii) from eq(i) and (ii) , DEAR > 5@*\$ In a certain code, FIND is coded as LOST and GEAR is coded as MUCH. How will GRID be coded in the same language? A) LOCH B) MHOT C) TUHM D) MCOT Correct Answer : MHOT Explanation :FIND = LOST GEAR= MUCH from eq(i) and (ii) , G=M, R=H ,I=O ,D=T therefore GRID > MHOT In a certain code ‘come back soon’ is written as ‘9 4 3’, ‘soon hear all’ is written as ’4 1 2’, and ‘come all’ is written as ‘2 9’, What is the code for ‘hear’? A) 1 B) 3 C) 2 D) 4 Correct Answer : 1 Explanation :‘come back soon’ = ‘9 4 3’ ------eq(i) ‘soon hear all’ = ’4 1 2’ ------eq(ii) ‘come all’ = ‘2 9’ ------eq(iii) from eq(i) and (ii), soon=4 from eq(ii) and (iii), all=2 Therefore, eq(ii) hear=1 In a certain code language LERNER is written as NGTPGT, STATES is written as UVCVGU, then how will SURELY be written in that code? A) ANGTWU B) UWTGAN C) UWTGNA D) TVCFMZ Correct Answer : UWTGNA Explanation :L-M-N E-F-G R-S-T N-O-P E-F-G R-S-T AND S-T-U T-U-V A-B-C T-U-V E-F-G S-T-U therefore, SURELY > UWTGNA If green’ is called ‘white’, ‘white’ is called ‘yellow’, ‘yellow’ is called ‘blue’, ‘blue’ is called ‘pink’ and ‘pink’ is called ‘black’, then what is the colour of sky? A) green B) blue C) pink D) yellow Correct Answer : pink Explanation :The colour of sky is 'blue' and as given 'blue' is called 'pink'. So, the colour of sky is 'pink'. If ‘black’ is called ‘red’, ‘red’ is called ‘white’, ‘white’ is called ‘brown’, brown’ is called ‘yellow’, ‘yellow’ is called ‘blue’ and ‘blue’ is called ‘green’, then what will be the colour of milk? A) blue B) green C) white D) brown Correct Answer : brown Explanation :The colour of milk is 'white' and as given, 'white' is called 'brown'. So, the colour of milk is 'brown'. If MADRAS is coded as NBESBT. How is BOMBAY coded in that code? A) CPNCPX B) CPNCBZ C) CPOCBZ D) CQOCBZ Correct Answer : CPNCBZ Explanation :Cearly, that in the above example each letter in the word MADRAS is moved one step forward to obtain the corresponding letter of the code. M is coded as N, A is coded as B and so on. M A D R A S N B E S B T So code for B O M B A Y is C P N C B Z If T A P is coded as S Z O Then code: F R E E Z E ?
