plzz answer fast❤❤​

Answer 1

Answer:

1800

Step-by-step explanation:

Given,

A = 2520, R = 10%, T = 4 years

We know that,

A = P(1 + TR/100)

=> 2520 = P(1 + 40/100)

=> 2520 = P(140/100)

=> 2520 * 100 = 140P

=> 252000 = 140P

=> P = 1800

Therefore, Sum = 1800

Answer 2

The Principal amount is ₹1800.

Given:

• A sum of money amounted to ₹2520.
• At 10% per annum in 4 years.

To find:

• Find the principal amount.

Solution:

Concept/formula to be used:

• $\boxed{\text{\bf Simple Interest}\bf = \frac{P \times R\times T}{100}}$

Step 1:

Write the given values.

Let the principal amount is ₹P.

So,

According to the question,

$P+SI= 2520$

$\bf SI= 2520-P$

$R= 10 \%$

$T= 4 \: years$

Step 2:

Find the principal amount.

Put the values in formula of simple interest.

$2520-P = \frac{P \times 10 \times 4}{100}$

$(2520 - P)5 = 2P$

$12600 - 5P = 2P$

$7P= 12600$

$\bf P = 1800$

Thus,

Principal amount is ₹1800.
