let the S.P of each banana be 1, then S.P of 180 bananas is 180 
loss = S.P of 20 bananas = 20

we know loss = C.P - S.P , then C.P = S.P + loss
so CP of 180 bananas = 180 + 20 = 200
Loss percent = @@\dfrac{\text{Loss}}{\text{CP}}×100=\dfrac{20}{200}×100@@

after cutting it we will find the answer is 10% loss

15*12-->180Rs
180----->180Rs
180----->160Rs (I.e loss of selling price of 20 bananas)
By Alligation Method:
180*180=32400 (C.P)
180*160=28800 (S.P)
-------
3600 (Loss)
(3600/32400)*100=11.11%loss

180cp-180sp=20sp

180cp=200sp

20/180*100=11.11 % loss

180cp=200sp .

suppose cost price of one article (cp) = 1
selling price of one article(sp) = 180/200 = 0.9
loss in selling one article = 0.1
loss = (0.1/1)*100 =10%

Last part of your calculation is wrong

Let selling price of 1 banana be Rs.1

Selling price of 15 dozen Bananas = 15*12*1 = Rs.180
Loss = selling price of 20 bananas = Rs.20
Cost price of 15 dozen Bananas = 180+20 = Rs.200
Loss percentage = 20*100/200= 10%

Let selling price of 1 packet is Rs.1

Then, selling price of 100 packets = Rs.100
Profit = selling price of 20 packets = Rs.20
Cost price = Rs.100- Rs.20 = Rs.80
Profit percentage = 20*100/80= 25%
