$at \: first \: we \: have \: to \: know \\ the \: formula \: of \: interest = \\ \frac{principle \times rate \: of \: interest \times time}{100} \\ from \: here \: we \: can \: write \\ rate \: of \: interest = \frac{100 \times interest}{principle \times time} \\ in \: the \: queation \: given \: that \\ principle(p) = 4510 \\ interest(i) = 110 \\ time = 6 \: months = \frac{1}{2} years \\ rate \: of \: inerest = \frac{100 \times i}{p \times t} \\ = \frac{100 \times 110}{4510 \times \frac{1}{2} } \\ = \frac{100 \times 110 \times2}{4510} \\ = \frac{100 \times 2}{41} \\ = \frac{200}{41} \\ = 4.879\%$

your answer is 4.879% ✔✔✔✔
