Question
Mr. Rajan got a job at the age of 24 years and he got retired from the job at the age of 60 years. What fraction of his age till retirement was he in the job?
Solution
Given, Rajan’s age on the joining = 24 years and retirement age = 60 years
∴ The fraction of his age till retirement, when he was in the job = `"Total years he did the job"/"Retirement age"`
= `36/60` .....[ ∵ HCF of 36 and 60 = 12]
= `(36 ÷ 12)/(60 ÷ 12) = 3/5`
Hence, the required fraction is `3/5`.
