:
C
It is given that Krishna's weight is 60 kg and Karan's weight is 80 kg. To balance the see-saw Krishna needs another person.
Let the required weight needed to balance the see-saw be xkg
Then, 60+x=80x=80−60=20
So, Krishna should take help of a kid who weighs exactly 20 kg. Thus, Pandu would be the correct selection.
