Directions for question :

A week before Durga Puja, a Traffic Police Inspector during his beat in front of the Regional Transport Office at Padmapukur, Kolkata, noticed 120 each of brand new private Sedans, Hatchbacks and SUVs and 30 4x4 Wheelers, which had applied for new registration, queued up along the road in front of the Regional Transport Office in order to get registered. The vehicles and their owners were blocking up a substantial portion of the very busy road for about a kilometer, leading to traffic snarls. 

On enquiry, the manager at the office showed the inspector on his desktop screen a currently updated table showing the data of the individual number of the four necessary documents whose verification has been completed, on all the private vehicles in queue. The manager explained that the time taken up to verify the documents was causing the delay in registration. 

The table on the desktop screen is reproduced below.

Total number of SUVs in the queue = 120

As per the table,

Number of SUVs whose Insurance Certificate verification is pending = 120 – 78 = 42

Number of SUVs whose Sales Invoice from dealer verification is pending = 120 – 102 = 18

Number of SUVs whose Identity Proof of owner verification is pending = 120 – 93 = 27

Number of SUVs whose filled up Form 20 verification is pending = 120 – 87 = 33

If all the SUVs above are distinct ones, 

Then the total number of SUVs whose only one document verification is pending = 42+18+27+33 = 120

Hence, a maximum of 120 SUVs cannot have verification completed of all the four documents necessary for registration.

Hence, the minimum number of SUVs in the queue whose registration can be processed immediately due to the completion of verification of all the four documents necessary for registration = 120 – 120 = 0
