Question

2. A certain sum amounts to R5.832 in 2 years at 8% if the interest is compounded annually. Find the sum
​

Answer 1

Answer:

Amounts =5.832

t=2years

r=8%

A=P(1+r/100)^n

RS5.832= p(1+8/100)^2

5.832=P(108/100×108/100)

5.832=1.1664p

p=5.832/1.1664

rs 5

Answer 2

let the sum or principal be rupee x

given,

Amount= rupee 5.832

time= 2 years

rate= 8%

CI= P{(1+r/100)^t-1)

5.832= P{(1+8/100)^2-1}

5832/1000=P×108/100×108/100-1

therefore,

P=5832×100×100/1000×108×108+1

P= rupee 6
