Loss = SP of 6 hens = 6k. ==> CP = SP + Loss = 144k + 6K = 150k.

Hence loss % = (Loss/CP) x 100 = (6k/150k) X 100 = 4 %.

---------------------------

Now if CP of 144 hens = Rs. 7200,

then SP of 144 hens at 4% loss = [(100-Loss%)/(100)]xCP

= [(100-4)/(100)]x7200 = Rs.6912.

Therefore SP of one hen = SP of 144 hens /No. of hens = 6912/144 = Rs.48
