Question

mr dubey borrow 100000 from a Bank at 1℅ per year compound interest . what amount he will pay after 3 year

Answer 1

We know the amount he borrowed is ₹100,000 (P) , the time is 3 years(n) and the rate is 1%(r) . Using the formula
A=p(1+r/100)^n we get 1,03,030.1 as the amount me Dubey has to pay after 3 years

Answer 2

hello,
compound interest formula
A=P(1+R/100)ⁿ
where A=total amount,P=principal,R=rate of interest,n no. of years 
P=100000  R=1% n=3 yrs
A=100000(1+1/100)³
A=100000×(101/100)³
A=100000×101/100×101/100×101/100
A=101×101×101/10
A=103030.1
therefore at the end of 3 years he will receive rupees 103030.1
