the avg weight of a , b & c is 84 kg . if d joins the group , the avg weight of the group becomes 80 kg . if another man e who weights is 8 kg more than d replaces a , then the avgof b , c , d & e becomes 79 kg . what is the weight of a ?
n0 = 84.0
n1 = 80.0
n2 = 8.0
n3 = 79.0
t0 = n1 * 4.0
t1 = n3 * 4.0
t2 = n0 * 3.0
t3 = t0 - t2
t4 = n2 + t3
t5 = t1 - t4
answer = t0 - t5
print(answer)
