Instructions

Study the following information to answer the given questions. In a certain code language, economy and work related’ is written as oj my bx st’ work and employment today’ is written as pk bx oj dy’ employment for growth only’ is written as ‘el pk fd zn’ growth is related today’ is written as ‘el dy gm my’ (All codes are two letter codes only)

Question 6: What is the code for ‘growth today’ in the given code language ?

a) fd el

b) dy fd

c) pk dy

d) dy el

e) an fd

Solution:

The common words in first two statements are ‘work’ and ‘and’ coded as = ‘oj’ or ‘bx’

The common word in first and last statements is ‘related’ coded as = ‘my’

=> Only word left in first statement is ‘economy’ coded as = ‘st’

The common word in second and third statements is ’employment’ coded as = ‘pk’

=> Only word left in second statement is ‘today’ coded as = ‘dy’

The common common word in last two statements is ‘growth’ coded as = ‘el’

=> Only words left in third statement are ‘for’ and ‘only’ coded as = ‘fd’ or ‘zn’

=> Only word left in last statement is ‘is’ coded as = ‘gm’

Thus, the code for ‘growth today’ = dy el

=> Ans – (D)

Question 7: Which of the following additional statements is required to definitely find the code of and’ in the given code language ?

a) ‘work and prosper now’ is written as bx yp jn oj’

b) ‘work today also important’ is written as ‘Iv en oj dy’

c) No additional statement is required to find the code

d) and more work today’ is written as z1 oj dy bx’

e) ‘related only for employment’ is written as ‘my zn fd pk’

Solution:

The common words in first two statements are ‘work’ and ‘and’ coded as = ‘oj’ or ‘bx’

The common word in first and last statements is ‘related’ coded as = ‘my’

=> Only word left in first statement is ‘economy’ coded as = ‘st’

The common word in second and third statements is ’employment’ coded as = ‘pk’

=> Only word left in second statement is ‘today’ coded as = ‘dy’

The common common word in last two statements is ‘growth’ coded as = ‘el’

=> Only words left in third statement are ‘for’ and ‘only’ coded as = ‘fd’ or ‘zn’

=> Only word left in last statement is ‘is’ coded as = ‘gm’

Thus, to definitely find the code of ‘and’, we need a statement that contains only one of ‘work’ or ‘and’

=> Ans – (B)

Question 8: What may be the code for economy is boosting’ in the given code language ?

a) gm rc st

b) zn gm st

c) ye st el

d) cp st rc

Solution:

The common words in first two statements are ‘work’ and ‘and’ coded as = ‘oj’ or ‘bx’

The common word in first and last statements is ‘related’ coded as = ‘my’

=> Only word left in first statement is ‘economy’ coded as = ‘st’

The common word in second and third statements is ’employment’ coded as = ‘pk’

=> Only word left in second statement is ‘today’ coded as = ‘dy’

The common common word in last two statements is ‘growth’ coded as = ‘el’

=> Only words left in third statement are ‘for’ and ‘only’ coded as = ‘fd’ or ‘zn’

=> Only word left in last statement is ‘is’ coded as = ‘gm’

Thus, the code for economy is boosting’ may be = gm rc st

=> Ans – (A)

Question 9: What does the code pk’ stand for in the given code language ?

a) growth

b) employment

c) only

d) economy

e) today

Solution:

The common words in first two statements are ‘work’ and ‘and’ coded as = ‘oj’ or ‘bx’

The common word in first and last statements is ‘related’ coded as = ‘my’

=> Only word left in first statement is ‘economy’ coded as = ‘st’

The common word in second and third statements is ’employment’ coded as = ‘pk’

=> Only word left in second statement is ‘today’ coded as = ‘dy’

The common common word in last two statements is ‘growth’ coded as = ‘el’

=> Only words left in third statement are ‘for’ and ‘only’ coded as = ‘fd’ or ‘zn’

=> Only word left in last statement is ‘is’ coded as = ‘gm’

Thus, the code pk’ stands for = employment

=> Ans – (B)

Question 10: If the code for ‘related people only’ is ‘xd my fd’ then what may be the code for ‘people for decision’ in the given code language ?

a) to xd my

b) zn xd fd

c) zn xd dy

d) zn kz xd

e) kz fd xd

Solution:

The common words in first two statements are ‘work’ and ‘and’ coded as = ‘oj’ or ‘bx’

The common word in first and last statements is ‘related’ coded as = ‘my’

=> Only word left in first statement is ‘economy’ coded as = ‘st’

The common word in second and third statements is ’employment’ coded as = ‘pk’

=> Only word left in second statement is ‘today’ coded as = ‘dy’

The common common word in last two statements is ‘growth’ coded as = ‘el’

=> Only words left in third statement are ‘for’ and ‘only’ coded as = ‘fd’ or ‘zn’

=> Only word left in last statement is ‘is’ coded as = ‘gm’

If the code for ‘related people only’ is ‘xd my fd’, => code for ‘people’ = ‘xd’

Thus, code for ‘people for decision’ = zn kz xd

=> Ans – (D)
