1.
What is Sonia's present age? | |
I. | Sonia's present age is five times Deepak's present age. |
II. | Five years ago her age was twenty-five times Deepak's age at that time. |
Answer: Option
Explanation:
I. S = 5D ![]() |
S | ....(i) |
5 |
II. S - 5 = 25 (D - 5) S = 25D - 120 ....(ii)
Using (i) in (ii), we get S = | ![]() |
25 x | S | ![]() |
- 120 |
5 |
4S = 120.
S = 30.
Thus, I and II both together give the answer. So, correct answer is (E).
