Rina8888 [55]

Answer:

A.102%

Step-by-step explanation:

Let cost price of painting=$100

In first year price increased 20%

Then , the price= $100+100(0.20)=$ $120

In second year

Price decreased 15%

Then , the price of painting= $120-120(0.15)$

The price of painting=$102

Percent = $\frac{final\;price}{Initial\;price}\times 100$

By using this formula

Then, we get

Percent of the original price= $\frac{102}{100}\times 100$

Percent of the original price=102%

Option A is true.
