Question

Find the simple interest on ₹68,000 at 16 2/3% per annum for a period of 9 months.
​

Answer 1

Step-by-step explanation:

SI = 68000 × 50/3 × 9 × 1/100

= 150 × 680

= 102,000

Answer 2

Answer:

The simple interest on the given amount is ₹ 8500.

Step-by-step-explanation:

We have given that,

Principle ( P ) = ₹ 68000

Rate of interest ( R ) = $\displaystyle{\sf\:16\:\dfrac{2}{3}\:\%\:=\:\dfrac{16\:\times\:3\:+\:2}{3}\:\%\:=\:\dfrac{50}{3}\:\%}$

Time period ( N ) = 9 months = $\displaystyle{\sf\:\dfrac{9}{12}\:years\:=\:\dfrac{3}{4}\:years}$

We have to find the simple interest.

$\displaystyle{\pink{\sf\:Simple\:interest\:=\:\dfrac{Principle\:\times\:Rate\:of\:interest\:\times\:Time\:period}{100}}}$

$\displaystyle{\implies\sf\:Simple\:interest\:=\:\dfrac{P\:\times\:R\:\times\:N}{100}}$

$\displaystyle{\implies\sf\:Simple\:interest\:=\:\dfrac{\cancel{68000}\:\times\:\dfrac{50}{\cancel{3}}\:\times\:\dfrac{\cancel{3}}{\cancel{4}}}{100}}$

$\displaystyle{\implies\sf\:Simple\:interest\:=\:\dfrac{170\cancel{00}\:\times\:50}{1\cancel{00}}}$

$\displaystyle{\implies\sf\:Simple\:interest\:=\:170\:\times\:50}$

$\displaystyle{\implies\underline{\boxed{\red{\sf\:Simple\:interest\:=\:Rs\:8500\:}}}}$

∴ The simple interest on the given amount is ₹ 8500.
