    Question

    Fabina borrows Rs 12,500 at 12% per annum for 3 years at simple interest and Radhs bororows the same amount for the same time period at 10% per annum compounded annually. Who pays more interest and by how much?

    Medium Open in App Solution Verified by Toppr We have,

    Principal value (p) = Rs 12,500

    Time (t) = 3years.

    Rate of interest (R) = 12% P.a.

    now, simple interest S.I. = 100 P×R×t ​ = 100 12500×12×3 ​

    =Rs4500 (for fabina)

    Again, Given that,

    principal value (p)=12,500

    Time(t)=3years Rate(R)=10%p.a. now, Amount (A) = P(1+ 100 R ​ ) n =12,500(1+ 100 10 ​ ) 3 =12,500(1+ 10 1 ​ ) 3 =12,500× 10 11 ​ × 10 11 ​ × 10 11 ​ =125× 10 1331 ​

    =Rs16,637.50 (For Radha)

    C.I. for Radha

    =Amount−principalvalue.

    =16,637.50−12,500 =4137.50

    Then, Fabina pays more interest

    =4,500−4137.50 =362.50Rs. Hence, Interest=Rs362.50

    Open in App Solution

    The correct option is C

    Fabina pays ₹362.50 more than Radha.

    Here, Principal (P) = ₹12,500, Time (T) = 3 years, Rate of interest (R) = 12% p.a

    We know that S.I. = P R T 100

    where, S.I. is the simple interest, P is the principal, R is the rate of interest per annum and T is the time(number of years).

    Simple Interest for Fabina =

    P × R × T 100 = 12500 × 12 × 3 100 = ₹4500. We know that C.I. = P [ 1 + R 100 ] n

    where, C.I. is the compound interest, P is the principal, R is the rate of interest per annum and n is the time(number of years).

    Amount(A) paid by Radha at the end of 3 years,

    A = 1500 ( 1 + 10 100 ) 3 = 12500 ( 1 + 1 10 ) 3 = 12500 ( 11 10 ) 3 = 12500 × 11 10 × 11 10 × 11 10 = ₹16,637.50 ∴

    C.I. for Radha = A - P = ₹16,637.50 - ₹12,500 = ₹4,137.50

    Hence, Fabina pays ₹362.50 (= ₹4,500 - ₹4,137.50) more interest than Radha.

    Fabina borrows ₹ 12,500 at 12% per annum for 3 years at simple interest and Radha borrows the same amount for the same time period at 10% per annum, compounded annually. Who pays more interest and by how much? 

    Solution:

    For Simple Interest:

    A = (P × R × T)/100 P = ₹ 12,500 T = 3 years

    R = 12% simple interest

    where , A = Amount, P = Principal, T = Time period in years and R = Rate percent

    Thus, Simple Interest paid by Fabina for 3 years at the rate of 12% per annum

    S.I. for 3 years = (3 × 12500 × 12)/100

    = 3 × 125 × 12 = 4500

    For Compound Interest:

    A = P[1 + (r/100)]n P = ₹ 12,500 n = 3 years

    R = 10% compounded annually

    Thus, Amount paid by Radha for 3 years at the rate of 10% p.a. compounded annually

    A = P[1 + (r/100)]n

    A = 12500[1 + (10/100)]3

    A = 12500(11/10)3

    A = 12500 × (11/10) × (11/10) × (11/10)

    A = 12500 × (1331/1000)

    A = 12500 × 1.331 A = 16637.50

    Compound Interest = A - P

    = 16637.50 - 12500 = 4137.50

    Since 4500 > 4137.50, Fabina paid more interest than Radha.

    Additional Interest paid by Fabina = 4500 – 4137.50 = ₹ 362.50
