M-J=2(M-K)

M-J==2M-2k

2k=M+J

st 1= only salary of J is given we are not aware of M&K not sufficient

st 2= Value of k is given plus from above equation we know that M+J=2k

we have all the 3 values. Hence avg= M+J+K/3=80000+40000/3=avg

Statement 2 sufficient. Answer-B

Sum of 21 values =400+80=480

n is fraction of total sum=80/480=1/6
