Detailed Solution

Concept- We are given the price of 100 mangoes as Rs. 125 so first we will find the price for 400 mangoes then that price will be CP and profit is given. So using that we can find the SP of one dozen mangoes.
CP=125×4=Rs.500
SP=500+100=Rs.600
SP of 12 mangoes=
= 600400×12
=64×12
=32×12
=18
Rs.18 per dozen.
Hence, the correct option is 2.
