Expert Answer:

Let the cost of 12 dozen banana be Rs x.

 

Ravi's banana : Amit's banana :: Ravi's cost : Amit's cost

 

4 dozen:12 dozen::Rs 120:Rs x

rightwards double arrow 4 over 12 equals 120 over x
rightwards double arrow x space equals space fraction numerator 120 cross times 12 over denominator 4 end fraction equals 360

 

Therefore, cost of 12 dozen bananas is Rs 360.
