SOLUTIONS:

S11. Ans.(a)

Sol. Wrong number = 5

Patterns of series

3036 ÷ 6 – 1 = 505

505 ÷ 5 – 1 = 100

100 ÷ 4 – 1 = 24

24 ÷ 3 – 1 = 7

7 ÷ 2 – 1 = 2.5

2.5 ÷ 1 – 1 = 1.5

So, there should be 2.5 in place of 5.

S12. Ans.(d)

Sol. Wrong numbers = 125

Pattern of series

120120 ÷ 13 = 9240

9240 ÷ 11 = 840

840 ÷ 7 = 120

120 ÷ 5 = 24

24 ÷ 3 = 8

8 ÷ 2 = 4

So, there should be 120 in place of 125.

S13. Ans.(b)

Sol. Wrong Number = 812

Pattern of Series

1050 – 12×2 = 1026

1026 – 12×3 =990

990 – 12×4 = 942

942 – 12×5 = 882

882 – 12×6 = 810

810 – 12×7 = 726

So, there should be 810 in place of 812.
