Answer:</h2>
The percentage of loss is 43%.
<h2>
Step-by-step explanation:</h2>
The first price was $210,000. He sold it for $120,000. First, we need to count how much money did he lost. We do it simply by 210,000-120,000 = 90 000. Then, we need to find out, what is 1% of the first price. We get it, If we divide 210,000/100 = $2100 Now, we divide the money he lost by one percent of the first price. 90,000/2100 = 42,85714 %. We round that to 43%. His percentage of loss is 43%.
