1) The priest told the devotes, "the bell is rung at regular intervals of 45 min. The last bell was rung 5 min ago. The next bell is due to the rung at 7 : 35 am. At what time did the priest give the information to be devotes?
Explanation :
Time of ringing last bell = (7 : 45- 0 : 45) = 7 : 00 am.
But it happened 5 min before the priest gave the information to the devotes.
Therefore, Time of giving information = 7 : 00 + 0 : 05 = 7 : 05 am.
