Question : The table given below shows the GDP of two countries in different five years.
| Country | ||
| Years | A | B |
| Y1 | 175 | 285 |
| Y2 | 200 | 300 |
| Y3 | 150 | 125 |
| Y4 | 75 | 85 |
| Y5 | 50 | 95 |
$K_1$ = The value of the average GDP of country A in all 5 years.
$K_2$ = The value of average GDP of country B in all 5 years.
What is the value of ($K_1 + K_2$)?
Option 1: 316
Option 2: 290
Option 3: 308
Option 4: 178
Correct Answer: 308
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.
