The ratio of the ages of a teacher and a student is 5:2,
respectively. If the difference between their ages is 18 years, then find the age of the student.Solution
ATQ,
Let the ages of the teacher and student be '5x' years and '2x' years, respectively.
ATQ:
'5x' - '2x' = 18
Or, 3x = 18
Or, 'x' = 6
Therefore, the age of the student = 2x = 2 × 6 = 12 years
