Question

find the rate per annum if compounded anually (ii) Principal=3136,Compounded anually=345,time=2years
​

Answer 1

Answer:

p - 3136 than t =2 yr I = 345 : r = 100 *I ÷ p *t = 178

Answer 2

Answer:

here is the answer

Step-by-step explanation:

Rate of interest = 5.35%

Step-by-step explanation:

Principal = Rs 3136

Compound interest = Rs.345

Amount = Principal +Compound interest = Rs 3136+ Rs.345 = Rs.3481

Time= 2 years

Formula : A=P(1+r)^tA=P(1+r)t

3481=3136(1+r)^23481=3136(1+r)2

\frac{3481}{3136}=(1+r)^231363481=(1+r)2

\sqrt{\frac{3481}{3136}}=1+r31363481=1+r

\sqrt{\frac{3481}{3136}}-1=r31363481−1=r

0.0535=r0.0535=r

Rate of interest = 5.35%
