Danny and Ian are munching on a jar full of candies. Had Danny eaten alone it would have taken him 5 minutes to finish the candies in the jar. Had Ian eaten alone it would have taken him 10 minutes to finish half the jar.
Since both of them are eating simultaneously, how long would it take them to empty the jar?
3 minutes and 20 seconds
6 minutes and 40 seconds
Danny's does in 5 minutes
Ian finishes half in 10 minutes i.e finishes the jar in 20 minutes
Therefore Combined rate will be
5/20= 1/T ==> T = 4 min
