    Answer: (4) None of these
    Explanation:-
    Amount doubles itself in every 5 years.
    Starting amount = 25, 00, 000
    End of the 5 years (in 2005), Amount is = 2 x 25, 00,000 – 50,000
    = 50, 00, 000 – 50,000 = Rs.49, 50, 000
    End of 2010, Amount is = 2 x 49, 00, 000 – 50, 000
    = Rs.98, 50, 000
    Amount in 2015 = 2 x 98, 00, 000  – 50, 000
    = Rs.1, 97, 00, 000
    Amount in 2020 = 2 x 1, 97, 00, 000 = 3, 94, 00, 000

    Hence, the amount in the year 2020 will be Rs.3, 94, 00, 000
