Amount = S.I + P.
Here P = 1760-160 = 1600.
160 = 1600*12*t/100.
Which gives t = 5/6 years.
Now, 5/6*12 = 10 months.
Here P = 1760-160 = 1600.
160 = 1600*12*t/100.
Which gives t = 5/6 years.
Now, 5/6*12 = 10 months.

On the amount of 1760/- he got T.D of 160/-
with rate of interest of 12%
So we can directly use the formula
T.D=(AMOUNT*R*T)/(100+[R*T])
with rate of interest of 12%
So we can directly use the formula
T.D=(AMOUNT*R*T)/(100+[R*T])

But formula should be
TD= (A*R*T)/(100+R)^t
isn't it??
TD= (A*R*T)/(100+R)^t
isn't it??

5/6 is the fractional months so we have to convert it into a calendar month.
So, we can say that if 1 year is equal to 12 months then how much year or month is equal to 5/6 (In cross multiplication).
