1)

By what percent is the average export of country T over all the given years more than the average export of country R over all the given years?


A) 13 $\frac{7}{11}$ %

B) 9 $\frac{1}{11}$%

C) 13 $\frac{5}{7}$%

D) 4 $\frac{7}{11}$%

E) 12 $\frac{1}{7}$%

Answer:

Option A

Explanation:

Total export of country T = 60 + 50 + 55 + 110 + 110 = 376

Average export of Country  T = $\frac{375}{5}$ = 75 Crore

Total export of country R = 50 + 55 + 70 + 90 + 65 = 330

Average export of Country R = $\frac{330}{5}$ = 66 Crore

Required % = $\frac{75-66}{66}\times100$ = $\frac{150}{11}$ % = 13 $\frac{7}{11}$ %
