Answer 2

The selling price of a lamp is Rs. 850+8.5x.

Step-by-step explanation:

Since we have given that

Cost price of lamp = Rs. 850

Profit % = x%

So, we need to find the selling price of a lamp.

So, the selling price of lamp would be

$\dfrac{100+x}{100}\times 850\\\\=8.5(100+x)\\\\=850+8.5x$

Hence, the selling price of a lamp is Rs. 850+8.5x.
