Answer / ishwarya

For 2 minutes green light blinks 4 times (2 times in 1 minute means 4 times in 2 minutes)
For the same two minutes starting at the same time red light blinks 3 times.
So for the first two minutes both the light together blinks 7 times.
2 mins---->7 times (7*(2/2))
4 mins---->14 times (7*(4/2))
6 mins---->21 times (7*(6/2))
8 mins---->28 times (7*(8/2))
....
60 mins---->210 times (7*(60/2))
