In 2011, global sales of brand C = 47000
In 2012, global sales of brand C = 112\(\%\) of 47000 = 52640
Total sales in USA in 2011 = 18\(\%\) of 47000 = 8460
Total sales in USA in 2012 = 134\(\%\) of 8460 = 11,336.4
Total sales of China in 2011 = 21\(\%\) of 47000 = 9870
Total sales of China in 2012 = 122\(\%\) of 9870 = 12041.4
Total sales in rest of the country in 2011,
= 47000 - (8460 + 9870)
= 47000 - 18330 = 28670
Total sales in rest of the country in 2012,
= 52640 - (11336.4 + 12041.4)
= 52640 - 23377.8 = 29262.2
Percentage increase in the rest of the countries,
\(=\frac{29262.2-28670}{28670}\times100\)
\(=\frac{592.2}{28670}\times100\)
\(=2\%\)(approx)
Hence, option C is the correct answer.The correct option is (C): 2%
