Given :
Weight of peter = 105 kg
Weight lose per week = 500 g or 1/ 2 kg
Let the number of weeks needed reach 90 kg of Weight be x. Then, according to question.
105 - 1/ 2 x = 90
105 - 90 = 1/ 2 x
15 = 1/ 2 x
x = 15 × 2
x = 30
So, if peter lose 500 g or 1/ 2 kg per week then it will take 30 week to reach 90 kg.
