उत्तर : 3. "1/6"
व्याख्या :
Answer: C) 1/6 Explanation: Given X can do in 10 days => 1 day work of X = 1/10 Y can do in 15 days => 1 day work of Y = 1/15 1day work of (X + Y) = 1/10 + 1/15 = 1/6 Given they are hired for 5 days => 5 days work of (X + Y) = 5 x 1/6 = 5/6 Therefore, Unfinished work = 1 - 5/6 = 1/6

(B) There is something wrong with a city that remains unperturbed even as its birds desert it.
(C) Thankfully, the situation is not as hopeless as it seems.
(D) Much as we try to defend the seemingly irreversible modern life of these cities, we can’t stop our hearts from crying when we realize that our rapidly degenerating urban eco-system isn’t generous enough to let these delicate winged creatures build tiny little nests in its nooks and crannies, sit in solitude, and rear offspring.
(E) And this desertion seems to be true with most metros in India where house sparrows have almost become a thing of the past.
