Answer 2

Answer:

23.75%

Step-by-step explanation:

If CP of 100 hens = Rs. 8000,

CP of 1 hen =    

CP of 20 hens =  * 20 = Rs. 1600

Gain earned by selling 20 hens = 5%

SP of 20 hens = (100+gain%)/100 * CP

          Gain = 7920 - 6400

                   = rs 1520

Gain% = gain/CP * 100=  

                                   = 23.75%
