1. his cost price = rs 16
so his selling price should be 1.15(16)
or rs 18.4 per dozen.
But you want the selling price per hundred

so :

18.4/12 = x/100
x = 100(18.4)/12 = 153.333...

(notice the fact that he bought 1200 eggs did not enter the calculation)

check:
cost price per dozen = 16
selling price per dozen = 18.4
percentage change = 18.4/16 = 1.15 ---> 15% increase

2. c.p of eggs per dozen=rs 16
s.p of eggs per dozen= c.p + profit
= rs 16 + 0.15*16
= rs 16 + 2.4
= rs 18.4
But you want the selling price per hundred
so :

18.4/12 = x/100
x = 100(18.4)/12 = 153.333...
