    Step-by-step explanation:

    Let the sum of money be 100 which amounts to 200 ( doubles itself ) in 6 years time. Interest on 100rs. Is 100. Putting the following in simple interest formula. You get

    100= 100*R*6/100

    R= 100/6

    Now when 100 will become 5 times i.e 500 the interest will be 400rs.

    Putting in simple interest formula

    400= (100*100/6*T)/100

    = 2400/100 = 24 years.
