Answers
Answer:
5 days
Step-by-step explanation:
he only exercises for 30 minutes every day and reduces 30 kg in 15 days. this means he reduces 2 kg per day. if he exercising for 3 times more than how much he does usually(three times 30 min is one and a half hour) than the weight he would reduce everyday will be 3 x 2 = 6
he is reducing 30 kg and if he reduces 6 kg evryday then he would reduce 30 kg in 30/5 days = 5days

Answer:
5 days
Step-by-step explanation:
he takes 15 days to reduce 30 kgs it means he loses 2 kgs per day
and if he excercise thrice the amount of time he used to do he will take three times less time to lose the same amount of weight so 15/3
therefore he loses the same weight in 5 days by doing one and a half hour excercise per day
