Question

$0.07816+\_\_\_\_\_\_\_-0.0010=0.08715,$ then the decimal in blank space will be:

• A. $0.07716$
• B. $0.00899$
• C. $0.00999$
• D. $0.09099$

Answer 1

The correct option is C

$0.00999$

Explanation for the correct option:

Lets take the missing value as $x$.

$\Rightarrow$ $\begin{array}{rcl}0.07816+\underline{x}-0.0010& =& 0.08715\end{array}$

$\Rightarrow$$\begin{array}{rcl}x+0.07816-0.0010& =& 0.08715\end{array}$

$\Rightarrow$ $\begin{array}{rcl}x+0.07716& =& 0.08715\end{array}$

$\Rightarrow$ $\begin{array}{rcl}x& =& 0.08715-0.07716\end{array}$

$\Rightarrow$ $\begin{array}{rcl}x& =& 0.00999\end{array}$

Thus, the missing value is $0.00999.$

Hence, option (C) is the correct option.
