To find :

The cost price of the rare stamp

Taken :

To find the rare stamp use this formula -:

$\boxed{\sf{C.P.=\dfrac{100\%-C\%}{100}\times S.P.}}$

Where,

C.P. = Cost price

C% = Commission percentage

S.P. = Selling price

Solution :

$:\implies\sf{C.P.=\dfrac{100\%-30\%}{100}\times9800}$

$:\implies\sf{C.P.=\dfrac{70\%}{1\cancel{00}}\times98\cancel{00}}$

$:\implies\sf{C.P.=70\%\times98}$

$:\implies\sf{C.P.=Rs.6860}$

So , the cost price of the rare stamp is ₹6860 .
