Vedclass · Answer

(C) To find the rate of interest $(R)$,we can use either statement.From statement $(I)$: Simple Interest $(S.I.)$ = $19$,Principal $(P)$ = $800$,Time $(T)$ = $3$ years. Using the formula $S.I. = (P 	imes R 	imes T) / 100$,we get $19 = (800 	imes R 	imes 3) / 100$,which allows us to solve for $R$.From statement $(II)$: The difference between Compound Interest $(C.I.)$ and Simple Interest $(S.I.)$ for $2$ years is given by the formula $Difference = P 	imes (R/100)^2$. Given $Difference = 15.76$ and $P = 800$,we can substitute these values to solve for $R$.Since both statements independently provide enough information to calculate the rate of interest,the correct answer is 'Either $I$ or $II$'.
