Question

8000 became 9261 in a certain intervel of time at the rate of 5p

Answer 1

Answer:

Time = 3 \: years\\C.I = Rs\:1261

Step-by-step

Given

Principal(P) = Rs 8000,

Amount(A) = Rs 9261,

Rate of intersest(R) = 5% p.a,

Let the number of times

interest paid = n

we know that

< /p >< p > A = P(1+R/100)n

➡️ 9261 = 8000(1+ 5/100)n

➡️9261/8000 = (1+ 1/20)n

➡️9261/8000 = (20+1/20)n

➡️(21/20)3 = (21/20)n

➡️3 = n

Since, I f a"'= a n  ➡ m = n

Therefore,.

Time = 3 years

C.I = Rs 1261
