Question

at what rate percent will rs2000 amount to 2315. 25 in 3 years at compound interest?

Answer 1

let the rate be R% ,
P =2000, A= 2315.25 T = 3 years
so, C.I.= A-P
= 2315.25 -2000
= 315.25
C.I. = P(1+r/100)³ - P
315.25 = 2000(1+r100)³-2000
315.25+2000= 2000(1+r/100)³
2315.25 /2000 = (1+r/100)³
³√231.25 / ³√2000 =
