Answer 1

Asian weight in 2005 is 0.8k kg

Solution:

Let say weight of Asian = B kg in year 2005

Now Asian weight increased by 25% from year 2005 to 2009

$\text{ Increase in Weight } = \frac{25}{100} \times B = 0.25B$

Asian Weight in 2009 = Asian Weight in 2005 + Increased Weight

$k = B + 0.25B\\\\k = 1.25B\\\\B = \frac{k}{1.25}\\\\B = 0.8k$

Thus, Asian weight in 2005 is 0.8k kg
