Solutions:
S1. Ans.(c)
Sol.
Position of the 2nd B is increasing by 1 from right to left.
S2. Ans.(b)
Sol.
87 – 69 = 18
135 – 117 = 18
S4. Ans.(d)
Sol.
Except painting, rest all are colours
S5. Ans.(d)
Sol.
16 × 2 = 32, 24 × 2 = 48, 36 × 2 = 72
32 × 2 = 64 ≠ 66
S6. Ans.(d)
Sol.
Except YWN, rest all three are -2 series
S8. Ans.(b)
Sol.
9 = 2 + 3 + 4, 16 = 3 + 4 + 9
29 = 4 + 9 + 16, 54 = 9 + 16 + 29
S9. Ans.(a)
Sol. +4 series
S10. Ans.(a)
So. R’s present age =4/13×117=36 yrs= 3x
⇒ x = 12
∴ S’s present age = 12 × 2 = 24 yrs
Let the required years be x
∴ ATQ,
(36+x)/(24+x)=15/11⇒x=9
