Rahul can finish one-fifth of his homework in one hour. Neha can finish three-sevenths of her homework in one hour and thirty minutes, and Riya can finish three-fourths of her reading in three hours and thirty minutes if all of them start their homework at noon. And can go to play as soon as they all finish their task, when can they begin to play if they take a break at 3.30 p.m. for thirty minutes

Answer: Rahul can finish his entire homework assignment in 5 hours.

Neha can complete her entire homework in 3.5 hours

Similarly, Riya can conclude her homework is 4 hours 40 minutes.

Therefore, they all started their work at 12 p.m. and took a 30-minute break around 3.30 p.m.

Neha can begin playing if she completes her schoolwork in 3 hours and 30 minutes.

12 p.m. + 3 hours 30 minutes = 3:30 p.m.

Rahul can start his play at  12 p.m. + 5 hours + 30 min break = 5:30 p.m.

Riya can begin playing at

12 p.m. + 4:40 p.m. + 30 min. break = 5:10 p.m.
