Question

if rupees 5000 become Rupees 6000 in 2 years what is the rate of interest per annum.​

Answer 1

Answer:

S. I =₹6000-₹5000=₹1000

S. I=PTR/100

₹1000=500×2×R/1000-100R

1000=100R

=100/1000

R=10%

Answer 2

Answer:

The rate of interest per annum is 10 %.

Step-by-step-explanation:

For the simple interest,

• Principal = Rs 5000
• Time = 2 years
• Amount = Rs 6000

We have to find the rate of interest.

Let the rate of interest be x %.

We know that,

Amount = Principal + Simple interest

⇒ Simple interest = Amount - Principal

⇒ Simple interest = 6000 - 5000

⇒ Simple interest = Rs 1000

We know that,

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

⇒ 1000 = ( 5000 * x * 2 ) / 100

⇒ 1000 = 50 * 2x

⇒ 1000 = 100x

⇒ x = 1000 / 100

⇒ x = 10 %

∴ The rate of interest per annum is 10 %.
