Question

the principal that amount to rs4913 in 3 years at 61/4 per annum compound interest compounded annually the principle amount is​

Answer 1

Principal=(P) let

Amount=₹4913=(A)

Time=3years=(n)

Rate=61/4% per annum

Amount=P(1+R/100)^n

₹4913=P(1+61/4*100)^3

₹4913=P(1+61/400)^3

₹4913=P(400+61÷400)^3

₹4913=P(461/400)^3

₹4913=P(461×461×461÷400×400×400)

₹4913=P*9,79,72,181/6,40,00,00

₹4913*6,40,00,000÷9,79,72,181=P

₹3209.40=P

Principal =₹3209.40
