Let five members of a team be a,b,c,d and e .
Assume x be the avg weight of a then a=x(given) -->eqn 1
(a+b)/2=x+1;
(a+b+c)/3=x+2;
(a+b+c+d)/4=x+3 --> a+b+c+d=4x+12; -->eqn2
(a+b+c+d+e)/5=x+4; putting the value of eqn1 and eqn2 in this eqn, we get
4a+12+e=5a+20; on solving
e=a+8;
Therefore the last player e is 8 kg heavier than first player a.
