Question

Calculate the simple interest on $ 6400 at 10% p.a. for 9 months. ​

Answer 1

Answer:

5760

Step-by-step explanation:

s=PTR/100

S= 6400×9×10/100

S=64×90

S=5760

Answer 2

Answer:

Simple interest on $ 6400 at 10% p.a. for 9 months = $480

Step-by-step explanation:

Given,

Principal = $ 6400

Rate of interest = 10%

Time period = 9 months

To find

Simple interest

Solution:

Recall the formula

Simple interest = $\frac{PTR}{100}$, where 'P' is the principal, 'T' is the time period and 'R' is the rate of interest

Here we have,

Principal = P = 6400

Time period = T = 9months = $\frac{9}{12}$ years = $\frac{3}{4}$ years

Rate of interest = 10%

Simple interest = = $\frac{PTR}{100}$

= $\frac{6400X\frac{3}{4}X10 }{100}$

= 16×3×10

= 480

∴Simple interest on $ 6400 at 10% p.a. for 9 months = $480
