2AFC = 12 Eggs + 6 Cups Flour + 2 cup Sugar
1DFC = 3 Eggs + 4 Cups Flour + 2 cup Sugar
Total 2 AFC + 1 DFC = 15 Eggs + 10 Cups Flour + 4 cup Sugar
Amount of materials left is (24Eggs + 30 Cups Flour + 10 cup Sugar ) - ( 15 Eggs + 10 Cups Flour + 4 cup Sugar ) = 9 Eggs + 20 Cups Flour + 6 cup Sugar
MAx No of Pound cakes possible is 9 Eggs + 20 Cups Flour + 6 cup Sugar / 2 Eggs + 4 Cups Flour + 1 cup Sugar ~ 4 ( As we have 9 Eggs only ), Answer must be (B)
