${\large{\bf{\orange{\clubs{\underline{Solution :}}}}}}$

The cost is doubled means :

we will multiply :

${\sf{\pink{ = Given \: value \times 2}}}$

${\sf{\purple{Cost \: of \: book \: in \: 2015 = Rs. 32.50}}}$

${\sf{\purple{Cost \: of \: book \: in \: 2016 = Rs. 32.50 \times 2 }}}$

${\bf{\boxed{\purple{ = Rs. 65.00}}}}$

${\sf{\purple{Cost \: of \: book \: in \: 2017 = Rs. 65.00 \times 2 }}}$

${\sf{\red{\boxed{= Rs. 130.00}}}}$

So,

${\mathfrak{\green{The \: cost \: of \: item \: in \: 2017 \: is \: Rs. 130.00 .}}}$
