Question

Calculate simple interest for 6400 for 6months for 10%per annum

Answer 1

Answer:

Rs 320

Step-by-step explanation:

Principal = Rs 6400

Interest = 10% p.a.

STEP 1: Find the interest for 1 year:

interest = 10% of Rs 6400

Interest = 0.1 x 6400

Interest = Rs 640

STEP 2: Find the interest for 1 months:

1 year = Rs 640

12 months = Rs 640

1 month = 640 ÷ 12

1 month = Rs 160/3

STEP 3: Find the interest for 6 months:

1 month = Rs 160/3

6 months = 160 x 6

6 months = Rs 320

Answer: The interest is Rs 320

Answer 2

P = Rs 6400

T = 6 months = 1 / 2 years

R = 10 %

•°• I = PTR / 100

= 6400 × 1 × 10 / 2 × 100

= 320

•°• Simple interest is Rs 320
