Total weight of A + B + C = 84 x 3 = 252 kg
Total weight of A + B + C + D = 80 x 4 = 320 kg
∴ Weight of D = 320 - 252 = 68 kg
Given, E = D + 3 = (68 + 3) kg = 71 kg
Total weight of B + C + D + E = (79 x 4) kg = 316 kg
∴ Weight of B + C = 316 kg - 71 kg - 68 kg = 177 kg
Weight of A only = 320 kg - 177 kg - 68 kg = 75 kg
Refer this method.
