Question

What is the principle amount of
money when the simple interest is Rs.
300. the rate is 5% and the time is 2
years?​

Answer 1

Answer:

Rate : 5%

Time : 2 years

interest : ₹300

prinsipal : 100× interest

time × rate

= 100× 300

5 × 2

= 30000

10

= ₹ 3000

amount = principal + interest

= 3000+ 300 = ₹ 3300

Answer 2

Answer:

The principal = Rs. 3000

The amount = Rs. 3300

Step-by-step explanation:

Given:

• Simple interest ( S.I. ) = Rs. 300
• Rate ( R ) = 5%
• Time ( T ) = 2 years.

To find:

• The principal ( P ).

Solution:

As we are provided with the simple interest, so here we will use simply use the formula of simple interest to find the principal. Putting the values in the formula and then doing the required calculations we can easily find out the principal.

We know simple interest is calculated on the original principal and if the sum amount and rate of interest is same, then the interest of every year is same.

Let's find out...

• S.I = (P × R × T)/100
• 300 = (P × 5 × 2)/100
• 300 × 100 = P × 5 × 2
• 30000 = P × 5 × 2
• 30000 = P × 10
• P = 30000/10
• P = Rs. 3000

∴ The required principal ( P ) = Rs. 3000

Now, let's find amount.

• A = P + S.I.
• A = Rs. ( 3000 + 300 )
• A = Rs. 3300

∴ The required amount ( A ) = Rs. 3300

Verification:

• S.I = (P × R × T)/100
• S.I. = (3000 × 5 × 2)/100
• S.I. = (3000 × 10)/100
• S.I. = 3000/10
• S.I. = 300

Hence Verified!!
