Answer 1

Answer:

5 Years

-------------------------

Question:In how many years will 7500 amount to 9000 at 4% p.a. simple interest?

To find:Time

Step by step explanation:

We have Given that,

------------------

• ✧principal=rs 7500
• ✧Amount=rs 900
• ✧Rate=4% per annum

-----------------

✧Simple interest=Amount-Principal

=9000-7500

=1500

---------------------------------------------------

✷ to find: Time

-----------

✷Time=SI×100/P×R

=1500×100/7500×4

=100/20

=5 Year

---------------------------------

✧ Answer is 5 Years

Answer 2

Answer:

The time period is off 5 years.

Step-by-step explanation:

In context to the question asked,

We have to find the time,

As per data given in the question,

We have,

Principal ( P ) = Rs. 7500

Amount ( A ) = Rs. 9000

Rate of interest ( R ) = 4%

We know that,

${\text} {Amount = Principal + Interest$

=> ${\text} {Interest = Amount - Principal }$

=> ${\text} {Interest = 9000 - 7500}$

=> ${\text} {Interest = 1500}$

The formula to be used for calculating time:-

$\text { Simple Interest }=\frac{\text { Principal } \times \text { Time period } \times \text { Rate of Interest }}{100}$

Now, substituting the given values:

$\Longrightarrow 1500=\frac{7500 \times T \times 4}{100}$

Simplifying it further,

$\Longrightarrow 75 \times T \times 4=1500$

$\Longrightarrow T=\left(\frac{1500}{75 \times 4}\right)$

$\Longrightarrow T=\frac{20}{4}$

$\Longrightarrow T=5$

Hence, the required time is 5 years.
