A businessman allows a discount of $10$% on written price. How much above the cost price must he mark his goods to make a profit of $17$% ?

note:
$xtimesfrac{90}{100}=xtimesfrac{117}{100}$

$frac{117}{90}times100=130$

so $30$%

is this right ?

Your calculation is a bit unclear, but you got the answer right.

If your businessman has a cost price of $P$, then to make a profit of 17% he should get at least $1.17P$ for his product.

Since he can give a discount of 10%, this $1.17P$ is 90% of the written price. Thus, the written price should be $frac{1.17P}{0.9}=1.3P$. This indeed corresponds with a written price that is 30% above the cost price.
