Answer: a
Explanation:
$$\eqalign{
& {\text{Let}}\,{\text{the}}\,{\text{present}}\,{\text{ages}}\,{\text{of}}\,{\text{Sameer}}\,{\text{and}}\,{\text{Anand}}\,{\text{be}}\, 5x\,{\text{years}}\,{\text{and}}\,4x\,{\text{years}}\,{\text{respectively}} \cr
& \frac{{5x + 3}}{{4x + 3}} = \frac{{11}}{9} \cr
& 9\left( {5x + 3} \right) = 11\left( {4x + 3} \right) \cr
& 45x + 27 = 44x + 33 \cr
& 45x – 44x = 33 – 27 \cr
& x = 6 \cr
& {\text{Anand’s}}\,{\text{present}}\,{\text{age}} \cr
& = 4x \cr
& = 24\,{\text{years}}\, \cr} $$
