The bus for Delhi leaves every 25 minutes. An enquiry clerk told that last bus for Delhi had already left 10 minutes to 2:00 p.m. At what time the next bus will leave for Delhi?
Interval between two leaving buses = 25 minutes Time to leaving the last bus = 1:50 p.m.
∴ Reqd. time for the next bus = 1:50 + 0:25 which = 2:15 p.m.
