Show Answer

Answer:

Correct Answer: A

Solution:

  • Average export of country $ T=\frac{60+50+55+100+110}{5}=\frac{375}{5}=75 $ Average export of country $ R=\frac{50+55+70+90+65}{5}=\frac{330}{5}=66 $

$ \therefore $ Required percentages $ =\frac{9}{66}\times 100%=\frac{150%}{11}=13\frac{7}{11}% $
