let the sum of money be Rs.100
Rate=25/4%
T=?

In simple int.

required int= 400-100=Rs.300

SI=prt/100
300=100*25*t/400
300=25t/4
300*4/25=t
48=t

it will take 48 years

nchiranjeeb: nope it will take 36 years let's take principal = x yrs then amount=4x then si = 4x - x = 3 then time = 100*3x*3/x*25 i.e 36 years

Answer:

Si = prt/100

300 = 100 × 25 × t/400

300 × 4/25 = t

48 = t

Hope it will be helpful ✌️
