Question

If the interest is 316, compound rate of interest is 5% p.a. and time is 3 years, find the principal.​

Answer 1

Answer:

p = Rs.2012.73

Step-by-step explanation:

p = ?

r= 5%

t= 3 years

Ci = rs 316

A = P ( 1 +R /100)³

we know A = P + Ci

so we can say that

P + 316 = P( 1 + 5/100)³

P + 316 = P(105/100)³

P + 316 = P(1.05)³

P + 316 = 1.157P

P - 1.157P = - 316

- 0.157P = -316

P = 316/0.157

P = Rs. 2012.73
