    3 eggs CP = 1
    => 1 egg CP= 1/3
    In the next hour he purchase 6 egges per rupee.
    1 egg CP= 1/6
    So, 2 egg CP = (1/3+1/6)= 3/6= 1/2
    => 1 egg CP = 1/4
    Again,
    9 eggs SP = 2
    => 1 eggs SP = 2/9
    Loss= (1/4-2/9)= (9-8)/36
    %Loss = (1/36)×4×100= 100/9= 11.11%[Answer]
