SI = PRT/100
SI = P * 20/3 * 3 / 100
SI = P/5
CI = P( 1 + r/100)n - 1
CI = P( 1 + (20/3) / (100) ] 3 - 1
CI = P( 16/15)3 - 1
CI = P [ 4096/3375 - 3375 / 3375 ]
CI = 721P / 3375
CI - SI = 46
721P/3375 - P/5
721P - 675P/ 3375 = 46
46P/3375 = 46
P = 46 * 3375 / 46
P = Rs 3375

Step-by-step explanation:
SI = PRT/100
SI = P * 20/3 * 3 / 100
SI = P/5
CI = P( 1 + r/100)n - 1
CI = P( 1 + (20/3) / (100) ] 3 - 1
CI = P( 16/15)3 - 1
CI = P [ 4096/3375 - 3375 / 3375 ]
CI = 721P / 3375
CI - SI = 46
721P/3375 - P/5
721P - 675P/ 3375 = 46
46P/3375 = 46
P = 46 * 3375 / 46
P = Rs 3375
