Answer 2

Answer:

Basit weight in 2009 = 0.8 kg

Step-by-step explanation:

Let say weight of Basit was  = B kg in year 2009

Now Basit's weight increased by 25% from year  2009 to 2014

Increase in Weight = (25/100) B  =  0.25B  kg

Basit Weight in 2014 = Basit Weight in 2009 + Increased Weight

=> k = B + 0.25B

=> k  = 1.25B

=> B = k/1.25

=> B = 0.8k

Basit weight in 2009 = 0.8 kg
