the weight of Arun will be 65 kg because in his view he is less than 72 kg but greater than 65 kg so the average will be 70 but in his brothers view he he will be greater than 60 but less than 70 kg so its average is 65 kg and in his mother's view he will not be greater than 68 kg so in all the 65 kg is common so the Arun age will be 65 kg
