RRB Paramedical Staff Nurse Model Paper 7

Let consecutive even numbers P, Q, R, S and T are $\mathit{n},\mathit{n}+2,\mathit{n}+4,\mathit{n}+6$ and $\mathit{n}+8$
$5\mathit{n}=530-20\Rightarrow \mathit{n}=\frac{510}{5}=102$
Consecutive even numbers are 102,104,106,108 and 110 .
$\mathit{Q}\times \mathit{S}=104\times 108=11232$
short trick:
Write two consecutive even number before 106 and two consecutive even number after 106 102,104,106,108,110
Here,
$\mathit{P}=102,\mathit{Q}=104,\mathit{R}=106,\mathit{S}=108$ and $\mathit{T}=110$
$\mathit{Q}\times \mathit{S}=104\times 108=11232$
