Given,
Interest, $I$ $=$ $R s 288$
Rate of Interest, $R %$ $=$ $4 %$
Time, $T$ $=$ $5$ years
Principal, $P$ $=$ ………………..
$P$ $=$ $\frac{100 \times I}{T \times R}$
Apply the formula ,
$P$ $=$ $\frac{100 \times 288}{5 \times 4}$
$=$ $\frac{28800}{20}$ ( divide $28800$ by $20$ , we get $1440$ )
Principal( $P$ ) $=$ $1440$ .
