Answer 1

Answer: After Tax Nominal Rate - 12.6%

After Tax Real Rate - 3.6%

Explanation:

Real Rate of return is defined as the nominal interest rate less inflation.

The After Tax Real Rate therefore caters for tax from the Nominal rate and then deducts Inflation.

The formula is,

= Nominal Rate( 1 - tax rate) - Inflation rate

= 14% ( 1 - 10% ) - 9%

= 14 ( 90% ) - 9

= 3.6%

The Nominal Rate is simply the Real Rate plus Inflation. The After tax real rate has already being found so the After Tax Nominal Rate is,

= 3.6 + 9

= 12.6%
