What is age of R after two years? I. Average age of A and N is 24 years and ratio of age of R to A is 2:3. II. N is 4 years elder than S and ratio of age of S to R is 1:2.
- only statement l
- Only statement II
- Both I and II together
- Both statements together are not sufficient
Correct answer: Both I and II together
Solution
Statement I: A+N=48, R/A=2/3 → R=(2/3)A. Alone: infinitely many solutions. Statement II: N=S+4, S/R=1/2 → N=(1/2)R+4. Alone: no absolute value. Together: (3/2)R + (1/2)R+4=48 → 2R=44 → R=22. After 2 years=24.
