16. In a certain code, RIPPLE is written as 613382 and LIFE is written as 8192. How is PILLER written in that code?
A. 318826
B. 318286
C. 618826
D. 328816
E. None of these
Explanation: ANSWER : 318826 Explanation : . From the coding pattern, it is clear that code for P is 3, for I is 1, for L is 8, for E is 2, and for R it is 6. So word PILLER will coded as 318826.
17. If LINGER is 123456 and FORCE is 56789, then FIERCE is
A. 345667
B. 456678
C. 345677
D. 556789
E. opt 5
Explanation: ANSWER : 456678 Explanation : . Letters R, E are common to LINGER and FORCE, and numbers 6 and 5 are common to their respective coding. Therefore, 5 and 6 will stand for RE but not respectively. Now, since word FIERCE has double E, therefore, either of 5 and 6 will appear twice in its coding. Besides, coding of FIERCE will have two numbers from coding of FORCE for letters F and C, and one number from coding of LINGER for letter I. Hence, coding of FIERCE will be 456678.
18. If PICTURE is coded as tuvwxyz, then PATCH would be coded as
A. wtzyv
B. twxyz
C. tqwvm
D. mtuvw
E. opt 5
Explanation: ANSWER : tqwvm Explanation : . Codes for P, T and C will be t, w and v respectively (direct coding), and codes for A and H will be letters other than which have appeared in coding of PICTURE. Hence, PATCH will be coded as tqwvm.
19. If FESTIVAL is coded as MBWJUTFG, then OPIUM would be coded as
A. NOHTL
B. NTHNO
C. NVJQP
D. MUIPO
E. opt 5
Explanation: ANSWER : NVJQP Explanation : . The word has been coded in such a way that last letter in the coded word is the next letter of the first letter of the basic word, second letter is next that of the second letter of the basic word and so on. Hence, OPIUM will be coded as NVJQP.
20. In a certain code, BOY is written as $*� and HOUR is written @*�0. How is RUBY written in that code?
A. 0 � $ �
B. 0 $ � �
C. � $ � 0
D. � � $ 0
E. None of these
Explanation: ANSWER : 0 � $ � Explanation : . It is clear from the coding pattern that codes for R, U, B and Y are 0, �, $ and �, respectively.
