How old is Sonia right now? I. Sonia's current age is five times that of Deepak's. II. Her age was twenty-five times that of Deepak five years ago.
A. I alone sufficient while II alone not sufficient to answer B. II alone sufficient while I alone not sufficient to answer C. Either I or II alone sufficient to answer D. Both I and II are necessary to answer
Explanation: D = S/5 I. S = 5D I. S = 5D I. S = 5D I. S = 5D I. S (i)S - 5 = 25 (D - 5) S = 25D - 120 S = 25D - 120 (i)We get S = 25 x S/5 - 120 by using I in (ii)4S equals 120.S is equal to 30.As a result, I and II combined provide the solution. So, the proper response is (E).
