If 6 years are subtracted from the present age of Arun and the remainder is divided by 18, then the present age of his grandson Gokul is obtained. If Gokul is 2 years younger to Madan whose age is 5 years, then what is the age of Arun ?
Answer: C
Let the Present age of arun is \(x \)
Gokul's age = 5-2 = 3
\(\therefore\) \(\frac{x-6}{18}=3\)
\(\Rightarrow x-6=54\)
\(x=60\)
Arun's present age = 60 years
