Formula for T.D = Amount * R * T /100 + (R*T).
Formula for B.D = Amount * R * T /100.
Given data:
B.D. 's amount = 1600,
T.D 's amount = 1680,
R = 15 %,
T = ?.
B.D = T.D ( given B.D is same as T.D).
Amount * R * T/100 = Amount * R * T/100 + (R*T),
1600 * 15 * T/100 = 1680 * 15 * T/100 + ( 15 * T),
On simplification we get, T = 1/3 years.
To convert years to months, multiply by 12.
T = 1/3 * 12 = 4 months.

1600-15% = 240
1680-1600 = 80
80/240 = 1/3 *"4/12 = 1/3" * 4 is no of months /12 is total months,
So, the answer is = 4 Months.
1680-1600 = 80
80/240 = 1/3 *"4/12 = 1/3" * 4 is no of months /12 is total months,
So, the answer is = 4 Months.

I think T.D is 1600 and B.D is 1680.
Then based on T.D formula this can be solved.

Why 1600 is taken in time calculation?
If Td is 1680.
If Td is 1680.
