I got 0.104

@oobleck plse see is it right or wrong

let the effective annual rate be i

so
(1+i)^1 = (1 + .10/12)^12
1+i = 1.1047...
i = .1047 or ..... % per annum

To find the effective rate that is equivalent to a nominal rate of 10% per annum compounded monthly, you can use the formula for compound interest:

Effective Rate = (1 + (Nominal Rate / Number of Compounding Periods)) ^ Number of Compounding Periods - 1

In this case, the nominal rate is 10% per annum and compounded monthly. So, the number of compounding periods in a year is 12 (12 months).

Plugging the values into the formula:

Effective Rate = (1 + (0.10 / 12)) ^ 12 - 1

Calculating the expression inside the brackets:

Effective Rate = (1 + 0.0083333) ^ 12 - 1

Evaluating the expression:

Effective Rate = (1.0083333) ^ 12 - 1

Computing the power:

Effective Rate = 1.104713 - 1

Calculating the subtraction:

Effective Rate = 0.104713

So, the effective rate that is equivalent to a nominal rate of 10% per annum compounded monthly is approximately 10.47%.
