4H
The sum of the weights of the man, woman, and child must be equal on both sides, so:M + T + F = S1kg + 3kg + 2H = S1kg + 3kg + 2(2H) = S1kg + 3kg + 4H = S
Therefore, S = 4H
4H
The sum of the weights of the man, woman, and child must be equal on both sides, so:
M + T + F = S
1kg + 3kg + 2H = S
1kg + 3kg + 2(2H) = S
1kg + 3kg + 4H = S
Therefore, S = 4H
