The table given below shows the GDP of two countries in different five years.

K1 = The value of average GDP of country A in all the 5 years.

K2= The value of average GDP of country B in all the 5 years.

What is the value of (K1 + K2) ?

308

K1 = The value of average GDP of country A in all the 5 years

= \(\frac{ 175 + 200 + 150 + 75 + 50}{5}\)

= \(\frac{650}{5}\)

= 130

K2= The value of average GDP of country B in all the 5 years

= \(\frac{ 285 + 300 + 125 + 85 + 95}{5}\) 

= \(\frac{ 890}{5}\) 

= 178

K1 + K2 = 130 + 178  = 308
