A boy is carrying a fish in one hand and a bucket full of water in the other hand. He hen places the fish in the bucket thinking that is accordance with Archimedes' principle he is now carrying less weight as the weight of the fish will reduce due to upthrust. Is he right ?

No, this trick will not help him. When the mangoes are placed in the bucket, their weight will be reduced due to upthrust but the weight of water will be increased by the same amount. So, the total weight carried by the man will remain same.
