The first statement of the number series have a wrong number in it. The wrong number is the value of A starting in the series of the second statement followed by the same pattern. You have to complete the series and find the value of the ‘?’ in the second statement.

**Statement I:** 40, 20, 30, 60, 262.5, 1181.25

**Statement II:** A, ___, ?

Option 1 : 45

The pattern of the first series is as follows:

40 × 0.5 = 20

20 × 1.5 = 30

30 × 2.5 = **75**

75 × 3.5 = 262.5

262.5 × 4.5 = 1181.25

Therefore, the wrong number in the series is ‘60’

Value of A = 60

Pattern of second series is:

60 × 0.5 = 30

30 × 1.5 = 45

∴ Value of ‘?’ is 45.
