Question

if the sum of rs. 7800 amount to rs. 8625 in 2 years then interest earned is?​

Answer 1

Answer:

Rate of interest = 5.28%

Step-by-step explanation:

Given,

sum P = 7800

Amount = 8625

Amount = sum + Simple Interest

8625 = P + S.I

8625 = 7800 + S.I

S.I = 825

S.I = (PTR)/100

=> 825 = ( (7800) (2) R )/100

=> 82500 = 15600 R

=> R = 825/156

=> R = 5.28 %
