Practice MCQ Questions and Answer on Coding and Decoding
51.
In a certain code JA KI MO PE means AT A FROG'S LEAP, MO LA KI SO means TAKE A LEAP AHEAD and RE BO JA NA means INSECTS ARE FROG'S DIET. Which of the following is code for AT in that language?
(A) a
(B) pe
(C) bo

In a certain code, RAIL is written as KCTN and SPEAK is written as CGRUM. How will AVOID be written in that code?
(A) FKQXC
(B) KQXCF
(C) KRXCF
(D) KQVCB
Solution:
All the letters of the word, except the last letters, are written in the reverse order and in the group of letters so obtained, each letter is moved two steps forward to get the code. Thus, we have : AVOID => IOVAD => KQXCF
53.
In a certain code ORCHESTRA is written as ARTSEORCH. How is DREAMLAND written in that code.
ORESTRA
(A) DNALMAERD
(B) DNALDREAM
(C) DNALMDREA
(D) LANDMDRED
Solution:
ORCHESTRA = ARTSEORCH Steps: 1) The third and fourth letter from begging are fixed at the end of the coded word. 2) The position of second letter and last letter of the word are interchanged in coded word. 3) Second from last and first from begging are interchanged. 4) Third from last and fifth from first are interchanged. Following the same steps for the DREAMLAND. We get DNALMDREA.
