Answer:

Step-by-step explanation:

1st bell (10 minute)             2nd bell (15 minute)                 3rd bell ( 20 minute)

          9.00                                  9.00                                         9.00

          9.10                                   9.15                                          9.20

          9.20                                  9.30                                         9.40

          9.30                                  9.45                                         10.00

          9.40                                  10.00

          9.50

          10.00

    10.00 am is common in all the three. So all the three will ring together at 10.00 am
