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?

Answer 1

Given, Rajan’s age on the joining = 24 years and retirement age = 60 years

The number of years, he did the job = Retirement age – Joining age

= 60 – 24

= 36 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`.
