An old woman had $80$ gold coins. She distributed $22$ of them between her $2$ daughters, $18$ of them between her $2$ sons, and half of the remaining to charity after the recent Biparjoy cyclone in Gujarat.
Based on the information, answer the following questions:
$(a)$ Which of the following numeric expressions is correct for evaluating the number of coins given to charity$?$
$(i) \{80-(22+18)\} \div 2$
$(ii)\ [80-(22 \div 2)+(18 \div 2)] \div 2$
$(iii)\ [80+\{(22+18) \div 2\}] \div 2$
$(iv)\ 80-[(22 \div 2+18 \div 2\}] \div 2$
$(b)$ Evaluate the numeric expression obtained in $(a).$
