Question

4) If manohar pays an interest of ₹ 750 for 2 years on a sum of 4,500. find the rate of interest.
​

Answer 1

Given :

⠀⠀⠀⠀⠀⠀⠀⠀⠀

• T = 2 years

⠀⠀⠀⠀⠀⠀⠀⠀⠀

• I = Rs 750

⠀⠀⠀⠀⠀⠀⠀⠀⠀

• P = Rs 4500

⠀⠀⠀⠀⠀⠀⠀⠀⠀

To find :

⠀⠀⠀⠀⠀⠀⠀⠀⠀

• Rate of interest (R) = ?

⠀⠀⠀⠀⠀⠀⠀⠀⠀

Step-by-step explanation :

⠀⠀⠀⠀⠀⠀⠀⠀⠀

We know that,

⠀⠀⠀⠀⠀⠀⠀⠀⠀

$\longrightarrow \: \sf \: I = \dfrac{PRT}{100}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀

Substituting the values,

⠀⠀⠀⠀⠀⠀⠀⠀⠀

$\longrightarrow \: \sf750 = \dfrac{4500 \times R \times 2}{100}$

$\longrightarrow \sf \: \: 750 = 45 \times 2\times R$

$\longrightarrow \sf \: \: 45 \times 2R = 750$

$\longrightarrow \sf \: \: R = \dfrac{750}{45 \times 2}$

$\longrightarrow \sf \: \: R = \dfrac{375}{45}$

$\longrightarrow \sf \: \: R = \dfrac{125}{15}$

$\longrightarrow \sf \: \: R = \dfrac{25}{3}$

$\longrightarrow \sf \: \: { \boxed{ \sf{ \blue{R = 8\dfrac{1}{3} \: \% \: p. a}}}}$

Therefore, rate of interest is$\sf \: 8\dfrac{1}{3} \: \% \: p. a$
