the only options that explains that % of goods sold in U.S that were manufactured by China and other countries(Japan, Germany and U.S) was 80% and 38% (totals more than 100%) is the option B
I am unable to understand y E is correct


U missed the argument .One word have made the difference :

From an article in the Wall Street Chronicle: Sales statistics of major electronics manufacturers with sales in the United States show that 80% of consumer electronics (such as televisions, DVD players, and computers) sold in the U.S. last year were manufactured in China.

From an article in Consumer Results Magazine: The results from last year's survey on consumer electronics choices show that while products made in China are still very popular, more and more Americans are buying products made in Japan, Germany, and the United States. These three countries combined account for 38% of products sold in the U.S. last year.

->1st is data of major manufacturing units.(80%)
->2nd is over all ...(38%,62%)
now in second part(over all) the % of Chinese product is decreasing..means some manufacturer are selling Chinese product in lesser volume than are major manu.--Weighted Avg is involved here ..

lets take an example
10 * 2 / 2 = 10 --AVG
now if we add 5 in the initial sum , the avg will go down..
20+5/3 = 8.3(appx)
if we add 15, the avg will go up
20+15/3 = 11.6 (appx)
