Question

At what rate percent per annum will a sum of
₹ 7500 amount to ₹ 8427 in 2years, compound
annualy?​

Answer 1

Answer:

6%

Step-by-step explanation:

Amount (A) = ₹8427

Principal (P) = ₹7500

Time (n) = 2 years

Let the Rate be R.

A = P (1 + R/100)ⁿ

=> 8427 = 7500 (1 + R/100)²

=> 8427/7500 = (1 + R/100)²

=> 2809/2500 = (1 + R/100)²

=> (53/50)² = (1 + R/100)²

=> 53/50 = 1 + R/100

=> 53/50 - 1 = R/100

=> 3/50 = R/100

=> R = 6%

Answer 2

Answer:

A=P×(1+R/100)^2

8427=7500(1+R/100)^2

8427/7500=1+R/100^2

2809/2500=(1+R/100)^2

(53/50)^2=(1+R/100)^2

53/50=1+R/100

53/50-1=R/100

3/50=R/100

50R=300

R=6

so, rate of percentage is 6%
