Yes, please check out two more methods to solve the same problem.

Short Solution:
90% of x = 117% of x
So, required % = 30%


Long Solution:
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 1.17P/0.9=1.3P. This indeed corresponds with a written price that is 30% above the cost price.
