Question

A man weighs 72kg.his wife weighs 15% less than her husband.and son weighs is 10% more than his mother.find the weight of son?

Answer 1

Answer :

Mass of The Man = 72 kg

Mass of His Wife = 15 % less than her husband = 72 - ( 72 * 15/100 ) = 72 - 10.8 = 61.2 kg

Mass of The Son = 10 % more than his mother = 61.2 + ( 61.2 * 10/100 ) = 61.2 + 6.12 = 67.32 kg

Therefore Mass of The Son is 67.32 Kg or His Weight is 659.736 N [ According to Real Physics Weight and Mass are Different ] ....... According to Normal World, Here Mass and Weight are same ..... So your answer is 67.32 kg
