Solution : Sum of GDP of country A in all the 5 years = 175 + 200 + 150 + 75 + 50 = 650 Average of GDP of country A in all the 5 years, $K_1$ = $\frac{650}{5}$ = 130 Sum of GDP of country B in all the 5 years = 285 + 300 + 125 + 85 + 95 = 890 Average of GDP of country B in all the 5 years = $\frac{890}{5}$ = 178 $\therefore K_2$ = 178 So, ($K_1+ K_2$) = 130 + 178 = 308 Hence, the correct answer is 308.
