Question

Two runners, Gopal and John running round a circular track complete one round each in 7 minutes and 14 minutes respectively. They start at the same time. During the first 30 minutes how many times Gopal crossed John on the track?

Answer 1

Gopal took 7 min and John took 14 min

In 30 min gopal can take 4 rounds as 4×7=28 min and more 7 min will go beyond limited time.

John can undergo 2 rounds as14×2=28

Now in this time gopal will cross John 3 times bcoz the nex time they will cross will be beyond the time
