Question

explain... please answer is 20​

Answer 1

Answer:

a)10

Step-by-step explanation:

Take LCM Of 2,3,5,6,10

LCM=60

So the bells will ring together after every 60 minutes i.e. 1 hour.

From 10 AM to 8 PM, we have 10 hours .

So in 10 hours, the bells will toll together 10/1 = 10 times.

Answer 2

Answer:

20

Step-by-step explanation:

It is verrryyyyy eaaasyyyy :)

Step 1: To find the next time they will ring again together... Just find lcm of 2,3,5,6 and 10

Which is 30....

Which means they will ring together again at 10:30 that is 30 minutes after 10.

Step 2: It is asked in the question that how many times will they ring TOGETHER until 8 pm.

So we know that they ring together at an interval of 30 minutes.

Step 3: Count how many hours are there between 10 am and 8 pm.... There are 10 hours between 10 am and 8 pm isn't it.

And how many minutes are there in an hour? 60

So there are two 30 minutes in an hour isn't it?

So just multiply the times it will ring together in an hour (which is 2 because they ring together at every 30 minutes) with how many hours is there between 10 am and 8 pm (which is 10 hours isn't it)

That is 2*10 = 20

Understood right... It was very easy... ;) PLZ MARK ME AS THE BRAINLIEST
