Correct Answer: 33


Solution : Let the present age of R be $11x$, and S be $17x$.
According to the given condition,
$\frac{11x-11}{17x-11} = \frac{11}{20}$
⇒ $220x - 220 = 187x-121$
⇒ $33x = 99$
$\therefore x = 3$
Thus, the present age of R = 11 × 3 = 33 years
Hence, the correct answer is 33 years.
