Solutions:
S1.Ans.(c)
Sol. In all other groups, the letters are alternate.
S2.Ans.(c)
Sol. All other groups end with small letters or contains odd numbers of letters.
S4. Ans.(b)
Sol. The pattern of the number series is as given below:
15 + 9 = 24
24 + 18 (= 9 + 9) = 42
42 + 27 (= 18 + 9) = 69
69 + 36 (= 27 + 9) = 105
105 + 45 (= 36 + 9) = 150
S6.Ans. (a)
Sol. Numbers are alternatively multiplied by 3 and divided by 2.
So, the next number = 54 ÷ 2 = 27.
S7.Ans.(c)
Sol. The pattern is 1 x 2, 2 x 3, 3 x 4, 4 x 5, 5 x 6, 6 x 7, 7 x 8.
So, the next number is 8 x 9 = 72.
S8.Ans.(b)
Sol. Each number is the proceeding number multiplied by -2.
So, the required number is -128.
