Question
If 3 years is subtracted from the present age of R and
the remainder is divided by 9, then the present age of his grandson A is obtained. If A is 4 years younger than M whose age is 10 years, then what is the age of R?Solution
M’s present age = 10 years A’s present age = 10 – 4 = 6 years Let the present age of R be x Then, A’s present age = (x -3)/9 Now, according to question (x -3)/9 = 6 x = 54 + 3 x = 57 years
