(6) HUNTER (F) wlabxk

What is the code used for the letter E?

Soln.
Ans: a

E is common to TANGLE, SATIRE and HUNTER. Their codes have in common: l and a. But 'a' appears in the code for FRIGHT which doesn't contain E. So we are left with 'l' as the answer.

Question 3

Directions: In column I, some words are given. In column II, their codes are given but they are not arranged in same order in which they are in column I. Study the letters in both the columns and find out the code to the letter given in each of the following questions.

Column I Column II
(1) SOUND (A) mbi
(2) ADDRESS (B) cjav
(3) CRUX (C) idaop
(4) NET (D) ijdtv
(5) CRONY (E) jdgotv
(6) CROWDY (F) blooppv

What is the code for the letter T?

Soln.
Ans: a

NET has 3 letters, so its code is mbi. Out of the four options we can see E/T is either m or b. Now ADDRESS is 7 letters and contains only E, but not T, so from its code bloopv we can see that E = b. Hence T = m.

Question 4

If in a code language CIRCLE is coded as XRIXOV, how would you code SQUARE in the same language?

HJFZIX.

HJFZIV.

HJFZVI.

HJFZLX.

Soln.
Ans: b

Letters in the basic word occupy the same position from the beginning as their respective letters in the coded word occupy from the last in the alphabetical order.

SQUARE should end in V because CIRCLE ends in V, it being XRIXOV. So HJFZIV is the only option that fits this rule, no need to check others.

Question 5

In a certain code language 'books are great friends' means '412 185 316 842', 'friends for ever after' means '751 316 472 631', 'speak for justice now' means '432 891 472 431' and 'now or never comes' means '369 378 431 486'. Then '472 431' is the code for which words?

for now

are great

ever after

never comes

Soln.
Ans: a

'for' is common to items 2 and 3. So 'for' = '472'. Next we can see that 'now' is common to items 3 and 4. So 'now' = '431'. Hence '472 431' should be 'for now' or 'now for'
