​

Answer 1

Answer:

Principal = Rs 32500

Principal = Rs 32500 Rate of interest per annum = 12.5 %

Principal = Rs 32500 Rate of interest per annum = 12.5 % Rate of interest per half year = 12.5/2 = 6.25 %

Principal = Rs 32500 Rate of interest per annum = 12.5 % Rate of interest per half year = 12.5/2 = 6.25 % Time = 3/2 year

Principal = Rs 32500 Rate of interest per annum = 12.5 % Rate of interest per half year = 12.5/2 = 6.25 % Time = 3/2 yearAmount at compound interest = P[1 + r/100]

Principal = Rs 32500 Rate of interest per annum = 12.5 % Rate of interest per half year = 12.5/2 = 6.25 % Time = 3/2 yearAmount at compound interest = P[1 + r/100]n = 32500[1 + 6.25/100]^2*3/2

Principal = Rs 32500 Rate of interest per annum = 12.5 % Rate of interest per half year = 12.5/2 = 6.25 % Time = 3/2 yearAmount at compound interest = P[1 + r/100]n = 32500[1 + 6.25/100]^2*3/2= 32500[1.0625]³

Principal = Rs 32500 Rate of interest per annum = 12.5 % Rate of interest per half year = 12.5/2 = 6.25 % Time = 3/2 yearAmount at compound interest = P[1 + r/100]n = 32500[1 + 6.25/100]^2*3/2= 32500[1.0625]³= 32500 x 1.1995

Principal = Rs 32500 Rate of interest per annum = 12.5 % Rate of interest per half year = 12.5/2 = 6.25 % Time = 3/2 yearAmount at compound interest = P[1 + r/100]n = 32500[1 + 6.25/100]^2*3/2= 32500[1.0625]³= 32500 x 1.1995= 38,983.75

Principal = Rs 32500 Rate of interest per annum = 12.5 % Rate of interest per half year = 12.5/2 = 6.25 % Time = 3/2 yearAmount at compound interest = P[1 + r/100]n = 32500[1 + 6.25/100]^2*3/2= 32500[1.0625]³= 32500 x 1.1995= 38,983.75Compound interest = 38,983.75 - 32500 = Rs 6,483.75

Principal = Rs 32500 Rate of interest per annum = 12.5 % Rate of interest per half year = 12.5/2 = 6.25 % Time = 3/2 yearAmount at compound interest = P[1 + r/100]n = 32500[1 + 6.25/100]^2*3/2= 32500[1.0625]³= 32500 x 1.1995= 38,983.75Compound interest = 38,983.75 - 32500 = Rs 6,483.75 Interest paid by laloo after 3/2 year = Rs 6,483.75
