There are two lights one is green another one is red. green blinks 2 times per a minute, red blinks 3 times per 2 minutes. If two lights are start at same time how many time they blink together in 1 hours.
Answer Posted / jegathish
Green light blink every 30 sec(2 times per minute), and red light blink every 40 sec(3 times per 2 minute)..
green blinks 30,60,90,120,...
red blinks 40,80,120,..
so every 2 minutes lights blink together ,which means 1 hour=60 min......
so 60/2 = 30 times both lights are blink together.
