First we should understand that Usha, Nisha and Easha are all babies. Babies do sleep the maximum time and they don’t go without sleep at all. Now let us see how it works out.
a) Easha drinks milk when Usha sleeps.
b) If Nisha is awake Easha doesn’t drink milk.
c) It never happens that both Usha and Nisha are sleeping.
Since we know the babies do sleep, both Nisha and Usha also sleep. When either of them sleep Easha drinks Milk. From the three observations cited, the observation of the father and the mother are wrong and the nurse is correct.
