Ok he has 4 Apples. Each Apple weighs approx 125 gram. So 4 Apples make 500 g Then avg weight of an human is 70 kg. So net weight becomes 70.5 kg His train is 7 min early. That means he must be moving fast. Avg speed of a high speed train is 104.333m/s . As ifs 7 min early and avg distance btwn 2 stations is 7km it adds an factor of 0.667 to the speed making it 105 m/s. Dividing that from speed of light ie. 3x10ˆ8 we get ratio of 0.02837x10ˆ8. multifying with 10"22(accounting Sun is moving and increasing entropy of universe) we get 0.02837x 10ˆ30 And that's his relativistic mass wrt. Sun. As his weight is 70.5kg weight of sun becomes 70.5x0.02837x10ˆ30 ie. 1.989x 10ˆ30 kg approx. Solved.
