    Answer 2110
    Let's see the process:
    Principal= 320
    Now the ratio of principal and amount after every 8 years= 4:9 (320:720)
    i.e. ratio of principal and amount is 2:3 in every 4 years.
    Now, the amount after 16 years and amount after 20 years= 2:3
    2 units= 320+1300= 1620
    3 units= 2430= amount after 20 years.
    So, CI after 20 years= 2430-320=2110

    2110
    Principal= 320
    Ratio of P:A after 8 yeses= 320:720=4:9
    Then for 4yrs ration of P:A= 2:3
    Now amount after 16years = principal+C.I.= 320+1300=1620
    We know ratio of P:A for every 4yr is 2:3 then here
    P(amount after 16yr):A(after 20yr)
    2:3
    1620:
    2=1620 then 3 is equal to 2430
    So Ci = 2430-320(principal)=2110😅

    • @SumitSirAcademy
      @SumitSirAcademy  3 месяца назад +2

      Double wala hee aata hai exam mein because time k aur kisi ratio ke liye manually karna possible nahi hai, uske liye calculator chahiye jo ki allowed nahi hai… that’s why examiner waisa question nahi de sakta 🙂
