    Answer : Option B

    Explanation :

    Population of village Y in 1997 = 30000 (given).

    Let the population of village V in 1997 be v.

    Then, 15 : 10 = 30000 : v     =>     v = \(\frac { 30000 *10 } { 15 } \) = 20000

    Now, population of village V in 1998 = 20000 + (10% of 20000) = 22000.

    Therefore Population of village V below poverty line in 1998 = 58% of 22000 = 12760.
