Kapil leaves his house 20 minutes before six in the morning, reaching Kamal's house in 25 minutes. They finish their breakfast in another 15 minutes and leave for their institute, which takes another 35 minutes. At what time do they leave Kamal's house to reach their institute?

6:20 am

The correct answer is Option (2) → 6:20 am

Kapil leaves his house 20 minutes before 6 a.m.

He takes 25 minutes to reach Kamal’s house.

→ Arrival at Kamal’s house = 5:40 a.m. + 25 min = 6:05 a.m.

They have breakfast for 15 minutes.

→ Finish breakfast and leave Kamal’s house at 6:20 a.m.

They leave Kamal’s house at 6:20 a.m.
