Question

find the time when
principle =500, Rate 7.5% ,simple interest =150 time=?
​

Answer 1

Given:-

• Principle = 500 ; Rate of interest = 7.5% and simple interest = 150.

To Find:-

• Find the time.

Solution:-

$\tt \mapsto { \: Simple \: Interest \: = \frac{PTR}{100} \: }$

$\tt \mapsto { \: Simple \: Interest \: = \frac{ \: 500 \: \times \: T \: \times \: 7.5 \: }{100} \: }$

$\tt \mapsto { \: 15000 \: = \: 3750T \: }$

$\tt \mapsto { \: T \: = \: \frac{15000}{3750} \: }$

$\boxed{\tt { \: T \: = \: 4 \: }}$

Answer 2

Answer:

$\rm \: →Simple \: interest= \frac{P×T×R}{100}$

$\rm→150 = \frac{500 \times t \times 7.5}{100}$

$\rm →15000 = 3750 \times t$

$\rm→T = \frac{15000}{3750}$

→ 4

So the required answer is 4
