Answer:
1. The length of the thread which is left on the reel is 790 cm. Given data : Total length = 10 m = 1000cm ( 1m = 100cm) Used = 210 cm. So the length of the remaining thread will be = (Total amount - Used amount) = 1000-210 = 790 cm. (Answer)
2. 105 -90 = 15kg 500g = 1/2 kg Peter is 15kg overweight. 15 x 2 = 30 It will take him 30 weeks for this.
