Solutions:
S1.Ans.(a)

S2.Ans.(d)
S3.Ans.(d)
Sol. All other groups contain alternate letters of the alphabet in order.
S4.Ans.(d)
Sol. In all other groups, the first two letters are alternate letters of the alphabet, while second and third letters occupy the same positions from the beginning and the end of the alphabet respectively.
S5.Ans.(b)
Sol. All other letters occupy the even-numbered positions in the English alphabet.
S6.Ans.(c)
Sol. Each letter in the first half is moved one step forward
while that in the second half is moved one step backward, to get the code.
COMPA/TIBLE -> APMOC/ELBIT -> BQNPDDKAHS
Similarly,
STABI/LISED -> IBATS/DESIL -> JCBUTCDRHK
S7.Ans.(a)
Sol. Words in a meaningful sequence:
2. Letter, 3. Envelope, 1. Post-box, 5. Clearance, 4. Delivery
S8.Ans.(a)
Sol. Clearly, each word is coded by the numeral which is 1 less than the number of letters in the word.
Since there are 7 letters in the word THEATRE, so required code = 7– 1 = 6.
S9.Ans.(d)
Sol. After changing signs according to the question, the new equation will be:
= 35 – 5 + 84 ÷ 4 – 1
= 30 + 21 – 1
= 50
S10.Ans.(a)
Sol. After changing signs according to the question, the new equation will be:
= 7 × 16 ÷ 2 – 46 + 10
= 7 × 8 – 36
= 20
