Step-by-step explanation:

Given, Toshiba bought 100 hens for Rs. 8000

and sold 20 at gain = 5 %

to gain 20 % in whole.

Cost price (CP) of 100 hens = Rs 8000

Cost price of 1 hen =  

100 8000 =Rs.80

So, cost price of 20 hens =20×80

=Rs.160

Gain % =  CP

SP−CP  100  5= 1600

SP−1600 ×100 SP=  100

5×1600  +1600=Rs.1680

∴ Gain on 20 hens = (1680 - 1600) = Rs .80

Now, cost price of 80 hens =80×80

=Rs.6400

Gain on 80 hens = ( SP - CP) of 80 hens

Gain on 100 hens = gain on 80 hens + gain on 20 hens  

∴ Gain on 100 hens = (SP - CP) of 80 hens + 80  

Gain % on 100 hens =  

CP of hens

Gain on 100 hens ×100

∴20= 8000

(SP of 80 hens - 6400 + 80 )  ×100  

∴ SP of 80 hens =  100

8000×20 +6400−80 =1600+6400−80=Rs.7920

∴ Gain of 80 hens =7920−6400=Rs.1520

∴ C.P. of 80 hens

Gain on 80 hens  ×100=gain %=  6400

1520  ×100=23.75%

So, the remaining hens should be sold at 23.75 % gain percent.
