How would I calculate this using a TI-84 calculator

a A bond has a par value of $1,000, a time to maturity of 20 years, a coupon rate of 10% with interest paid annually, a current price of $850, and a yield to maturity of 12%. Intuitively and without using calculations, if interest payments are reinvested at 10%, the realized compound yield on this bond must be 10.00%. 10.9% 12.0%. 12.4%. None of the options are correct
