Correct Option: B
As per the given question ,
Avocado [ Pink + Orange ]
It can be prepared directly or other different way to calculate least the cost / litre
Avocado [ Pink + Orange ] = ( 22 + 28 ) / 2 = 20
Avocado Pink [ Red + Yellow ] = [ 18 + (20 + 25) / 2 = 20.25
Avocado [ Red + White ] + Orange = [ (20 + 15) /2 + 22 ] / 2 = 19.5
Avocado [ Red + White ] + [ Red + Yellow ] = [ (20 + 25) / 2 + ( 20 + 15 ) / 2] / 2 = 19.5
