Step-by-step explanation:
Given,
Principal = Rs. 800
Rate = 10%
Amount = 926.10
Formula:
A = P (1 + r/100)t
If interest compounded semi-annually, then
Rate = r/2
Time = 2t
Calculation:
As given, interest compounded semi-annually, then
Rate = 10/2 = 5%
Time = 2 × t
According to the question
926.1 = 800 (1 + 5/100)2t
⇒ (1 + 1/20)2t = 926.1/800
⇒ (21/20)2t = 9261/8000
⇒ (21/20)2t = (21/20)3
Comparing on power
⇒ 2t = 3
∴ Required time = 3/2 = years
Answer:
0.667%
principle 12000
time 10 years
simple interest 800
so 800 for 10 years is 80 rupees for 1 year
so interest rate is (80/12000)*100 = 0.667
