The default value of byte-count is 1500 in custom queuing. You have 4 queues.
For 1st queue byte-count is 5000, 2nd queue - 3000, 3rd - 500 and 4th - 1500 (by default).
The bandwidth allocation of e0/1 in consideration of byte-counts would be
For 1 queue - 5000/sum_of_bytes * 100% = 5000/(5000+3000+500+1500) * 100% = 50%
and so on for other queues.

Subject: QOS task please advice
Dear All,
the task says to convert the legacy QOS into MQC on R5 ethernet
interface
the Legacy QOS is below
interface e0/1
custom-queue-list 1
queue-limit protocol ip 1 tcp www
queue-limit protocol ip 2 tcp ftp
queue-limit protocol ip 2 tcp ftp-data
queue-limit protocol ip 3 tcp telnet
queue-limit 1 default 4
queue-list 1 queue 1 byte-count 5000 limit 30
queue-list 1 queue 2 byte-count 3000
queue-list 1 queue 3 byte-count 500
the solution says that
policy-map QOS
class HTTP
bandwidth percent 50
queue-limit 30
class FTP
bandwidth percent 30
class TELNET
bandwidth percent 5
policy-map PARENT
class class-default
shape average percent 100
service-policy QOS
!
interface Ethernet0/0.52
service-policy output PARENT
I don't know how the bandwidth percent 50 for the HTTP traffic cames from
Please advice
