Aryan is 3 kg heavier than Bobby but 6kg lighter than Hina.The average weight of the three children is 30kg.What is the weight of bobby?

Answer»

let ARYAN's WEIGHT be x KG

then, bobby's weight = x-3 kg

and, hina's weight= x+6 kg

x+x-3+x+6=3*30

3x+3=90

3x=87

x=29 kg

Therefore, Bobby's weight=29-3 kg=26 kg
