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?
Answer: A
Let the present ages of Sameer and Anand be \(5x\)years and \(4x\)years respectively.
then \(\frac{5x+3}{4x+3}= \frac{11}{9}\)
\(\Rightarrow\) \(9\left ( 5x+3 \right )=11\left ( 4x+3\right )\)
\(\Rightarrow\) \(45x+27=44x+23\)
\(\Rightarrow \) \(45x - 44x = 33 - 27\)
\(\Rightarrow \) \(x = 6.\)
\(\therefore \) Anand's present age \(= 4x = 24 years\)
