Step-by-step explanation:

Take lcm of 4,6,8

Which is 24

That means three pressure cookers whistle together after 24 seconds

They are asking at what time will they whistle together for the 7th time

At 8:00am all whistled together that means from after 6 times of 24 seconds all the cookers will whistle together for 7th time

Multiply 24 by 6

24*6=144seconds

After 144 seconds all three pressure cookers will whistle together 7th time

Convert 144 seconds to minutes by dividing it by 60

144/60=2.4minutes =2 minutes 24 seconds

Now 8:00am +2minutes 24 sec will be

8:02:24 am

The time at which all cookers whistle together for 7th time
