**Note**: **In such questions, we are required to follow the instructions given in question very carefully. Now we will solve these questions one by one.**

**Q1:-**If A takes 25 min to reach railway station and his train is scheduled at **#&** then at what time should he leave to reach the station 5 minute earlier?

**Solution:**– First of all decode the time given in the coded form since the first symbol represents hour and # means Hour/minute hand on 5. It means time is 5 hrs. past & minutes. As the second symbol represents minutes and & means hour/minute hand at 2. Therefore the time is 5 hours 10 minutes PM.

He takes 25 minutes to reach railway station and he wants to reach 5 minutes earlier which means he has to leave home 30 minutes earlier. Now subtract these, minutes from the time of train and that is 5:10 pm. The result will be 4:40 pm. Now code this time in symbols and the answer is **(d) $ @.**

**Q2:-** If a train departed from a station at &£ and it takes 2 hours to reach the destination then when it will reach to the destination?

**Solution**: – The code &£ stands for 02:15 PM, Now add 2 hours to it, it becomes 04:15 PM. The code for 04:15 is** (A) $£.**

**Q3.** A person has to catch a train that is scheduled to depart at ‘@%’. It takes the person 4 hours and 15 minutes to reach the railway station from his home. At what time should he leave from his home for the railway station to arrive at the station at least 25 minutes before the departure of the train?

**Solution**: – The code @% stands for 08:00 PM, To reach station 25 minutes in advance and the time required to reach station is 04 hrs. and 15 minutes, the total time is 04 hrs. and 40 minutes. Therefore he should leave home at 03:20 PM. The code for this time is **(B) £$**
