UP Police Constable Exam Model Paper 5

Given:
Selling price of the Tablet $={\mathit{R}}_{\mathit{s}},15,300$
Discount $\%=15\%$
Formula Used:
$\mathit{M}\mathit{P}=\mathit{S}\mathit{P}\times \{100(100-$ Discount $\%)\}$
where, $\mathit{M}\mathit{P}=$ Marked Price
$\mathit{S}\mathit{P}=$ Selling Price
Calculation:
To find the actual price we need to find the Marked Price.
So, $\mathit{M}\mathit{P}=\mathit{S}\mathit{P}\times \{100/(100-$ Discount $\%)\}$
$\Rightarrow \mathit{M}\mathit{P}=15,300\times \left\{100/\left(100-15\right)\right\}$
$\Rightarrow \mathit{M}\mathit{P}=15,300\times \left(100/85\right)$
$\Rightarrow \mathit{M}\mathit{P}=\left(900\times 100\right)/5$
$\Rightarrow \mathit{M}\mathit{P}=90,000/5$
$\Rightarrow \mathit{M}\mathit{P}=18,000$
$\therefore$ The actual price of the Tablet is Rs. 18,000 .
