It's correct during non-monsoon periods only 1/20th to 1/30th of design discharge will be passing through the sewers if the combined system is adopted.

21 = 100%.
1 = 100/21.
4.76 = 100 * 4.76/21 = 22 = 20.
1 = 100/21.
4.76 = 100 * 4.76/21 = 22 = 20.

Qd/Qs=20.
So, Qd=20xQs.
Q= Qd+Qs.
Q= 20Qs+Qs. = 21Qs.
So, Qd=20xQs.
Q= Qd+Qs.
Q= 20Qs+Qs. = 21Qs.

How come 21 here?

Ans is 5.
Q= Qd+ Qs = 21 Qs (wet weather) and Q =0 +Qs in dry weather. So discharge in dry weather is (1/21) * 100 = approx 5%
Q= Qd+ Qs = 21 Qs (wet weather) and Q =0 +Qs in dry weather. So discharge in dry weather is (1/21) * 100 = approx 5%
