Question

$\begin{array}{ccccccc}220& 182& 146& 114& 84& 58& P\end{array}$

In each of the following questions a number series is given. A number in the series is suppressed by 'P' mark. First find out the number in the place of P' mark and use this number to find out the answer of the question following the series.

Find $P\times \frac{1}{\sqrt{256}}$.

• A. $2\frac{1}{8}$
• B. $2$
• C. $2\frac{1}{4}$
• D. $3\frac{7}{8}$

Answer 1

Answer: (A)

$2\frac{1}{8}$

First, let find the difference between the series

$220$ $182$ $146$ $114$ $84$ $58$ $P$

$38$ $36$ $32$ $30$ $26$ $x$

$2$ $4$ $2$ $4$ $2$ $4$......

$\therefore x=26-2=24$

$\therefore P=58-24=34$

$\therefore P\times \frac{1}{\sqrt{256}}$

$\Rightarrow 34\times \frac{1}{16}=2\frac{1}{8}$

Hence, the answer is $2\frac{1}{8}$.
