    Answer : Option B

    Explanation :

    Average decrease in weight per person = 2kg

    There are 10 men so total decrease in weight on replacing a man with a new man = 10 ∗ 2= 20 kg

    Weight of the man who is replaced = 60 kg

    ∴The weight of the new man would be = Weight of man replaced - total decrease in weight of the group of 10 men.

    = 60 - 20 = 40 kg
