Solutions:
S1.Ans.(a)
Sol. ‘253’ -> ‘books are old’ …….(i)
‘546’ -> ‘man is old’ …….(ii)
‘378’ -> ‘buy good books’ …….(iii)
In (i) and (ii) statements, So ‘5’ means ‘old’.
In (i) and (iii) statements, So, ‘3’ means ‘books’.
Thus, in the (i) statement ‘2’ means ‘are’.
S2.Ans.(d)
Sol. 8 is coded as E, 6 as K, 2 as D, 9 as J, 4 as B, 1 as L.
So, the code for 862941 is EKDJBL.
S3.Ans.(d)
Sol. BRANCH
S4.Ans.(c)
Sol. The letters in the series are alternate and the numbers indicate their position in the English alphabet from the beginning.
S5.Ans.(c)
Sol. Each letter in the word is moved one step forward to obtain the corresponding letter of the code.
S6.Ans.(c)
Sol. Clearly, each word is coded by the numeral which is twice the number of letters in the word.
So, DOLL = (Number of letters in DOLL) × 2 = 4 × 2 = 8.
S7.Ans.(d)
