Seven people Anuj, Akash, Bablu, Dharmendra, Ritu, Sudha and Ranjan are standing in a single line, facing a house. Ritu is somewhere ahead of Sudha. There is exactly one person standing between Bablu and Ranjan. Dharmendra is immediately behind Anuj, Sudha is behind both Akash and Dharmendra. If Dharmendra and Bablu are fourth and fifth in line respectively, then which of the following must be true?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → Sudha is sixth
The line faces the house, so the person nearest the house is 1st, and “behind” means farther from the house.
Dharmendra is 4th and Bablu 5th (given). Dharmendra is immediately behind Anuj, so Anuj is 3rd.
One person stands between Bablu and Ranjan, so Ranjan is 3rd or 7th; 3rd is Anuj’s, so Ranjan is 7th.
Sudha is behind Dharmendra, so she is 5th, 6th or 7th; 5th and 7th are taken, so Sudha is 6th.
Ritu and Akash are left with 1st and 2nd. Both conditions on them hold either way (Ritu ahead of Sudha, Akash ahead of Sudha), so their order is not fixed and only Sudha’s place must be true.
