Find the rate per cent per annum if :
$R s 350$ yields $R s 105$ interest in $6$ year.

Open in App

Solution

Given that,
Principal $P = R s . 350$
Rate $= R %$ p.a
S.I. $= R s . 105$
Time $T = 6 y e a r s$

$∵ S . I = \frac{P T R}{100}$

$⟹ 105 = \frac{350 \times 6 \times R}{100}$

$⟹ 105 = 21 R$

$⟹ R = \frac{105}{21}$

$⟹ R = 5$

$∴ R a t e = 5 %$ p.a.
