Present ages of Sameer and Anand are in the ratio of 5 : 4 respectively. Three years hence, the ratio of their ages will become 11 : 9 respectively. What is Anand’s present age in years?

A. 24 B. 27 C. 40 D. Cannot be determined Answer: Option A
Let the present age of Sameer and Anand be 5x and 4x respectively. $\begin{array}{l}\text{ Then, }\frac{5x+3}{4x+3}=\frac{11}{9}\\ \Rightarrow9(5x+3)=11(4x+3)\\ \Rightarrow45x+27=44x+33\\ \Rightarrow45x-44x=33-27\\ \Rightarrow x=6\\ \therefore\text{ Anand’s present age }\\ =4x\\ =24\text{ years }\end{array}$
