Explanation:

If the mean is 11 and there are 5 numbers then their sum is 5×11=55

We have the ratio of parts being a:b:c:d:e→1:2:3:4:5 so the total count of parts is 1+2+3+4+5=15

5 numbers mean = 11      5 x11= 55

there are  1+1+2+3+4 = 11 parts    each part = 5

 

the largest number has 4 parts of the 55       55/11 x 4 = 20 = biggest number
