Question

rate of interest=10 years=4 Amount=1330.To find principal and interest???​

Answer 1

Answer:

The principal and simple interest are Rs 950 and Rs 380 respectively.

Step-by-step-explanation:

We have given that,

• Rate of interest ( R ) = 10 %
• Time ( N ) = 4 years
• Amount = Rs 1330

We have to find principal and simple interest.

Let the principal be Rs P.

We know that,

Amount = Principal + Simple interest

⇒ 1330 = P + Simple interest

Simple interest = ( Principal * Rate * Time ) / 100

⇒ 1330 = P + ( P * R * N ) / 100

⇒ 1330 = P + ( P * 10 * 4 ) / 100

⇒ 1330 = P + ( 4P / 10 )

⇒ 1330 = ( 10P + 4P ) / 10

⇒ 1330 * 10 = 10P + 4P

⇒ 13300 = 14P

⇒ P = 13300 / 14

⇒ P = 950

Principal = Rs 950

Now,

Amount = Principal + Simple interest

⇒ Simple interest = Amount - Principal

⇒ Simple interest = 1330 - 950

⇒ Simple interest = Rs 380

∴ The principal and simple interest are Rs 950 and Rs 380 respectively.
