Congress: A-C-D-E A-B-D-E A-B-C-E B-C-E A-C-D

Street B-D cannot be used for a political procession on Thursday due to a religious procession. The district administration has a policy of not allowing more than one procession to pass along the same street on the same day. However, the administration must allow all parties to take out their procession during these two days.

 Q. Common Information Question: 2/2 Which of the following is not true?
 ✖ A. Congress and SP can take out their processions on the same day ✖ B. The CPM procession cannot be allowed on Thursday ✖ C. The BJP procession can only take place on Friday ✔ D. Congress and BSP can take out their processions on the same day

Solution:
Option(D) is correct

$\because$ Route BD cannot be used on Thursday.

∴ BJP has to take out its procession on Friday.

$\because$ Route DE is common to BJP and Congress.

∴ Congress should take out its procession on Thursday.

$\because$ Route AB is common to SP and BJP.

∴ SP should take out its procession on Thursday.

∴ BSP and CPM have to take out their processions on Friday.

∴ Congress procession can be allowed only on Thursday.
