Answer:

  • The reduction is 8.6%

Explanation:

Call F the full monthly pension of a person retiring at 62.

If a person continues to work the pension grows at a rate of 6% per year, compounded monthly, so use the compounded growing formula:

  • [tex]Pension=F(1+r/12)^{12t}[/tex]

Where r = 6 / 100 = 0.06, and t = number of years after retirement.

For retirement at 65.5:

  • t = 65.5 - 62 = 3.5

  • [tex]Pension=F(1+0.06/12)^{12\times 3.5}=1.233F[/tex]

For retirement at 67:

  • t = 67 - 62 = 5

  • [tex]Pension=F(1+0.06/12)^{12\times 5}=1.349F[/tex]

Percent reduction of people who retire at 65.5 compared to what they would receive at 67:

  • [tex](1.349F-1.233F)\times 100/(1.349F)=8.6\%[/tex]
