उत्तर
P =Rs 50,000 ; A= Rs (50,000 + 32,151.60) =Rs 82,151.60 ; r = 18% ; t = ?
`"A" = "P" (1 + "r"/100)^"n"`
Rs 72,151.60 = Rs 50,000 `(1 + 18/100)^"n"`
`82151.60/50000 = (1 + 18/100)^"n"`
`8215160/(50000 xx 100) = (1 + 18/100)^"n"`
`205379/125000 = (1 + 18/100)^"n"`
`(59)^3/(50)^3 = (59/50)^"n"`
t = 3
T = 3 years
