The true discount on Rs.1664 due 4 months hence is Rs.64. The rate percent is:

Siddartha Mulumudi   8 years AGO

Present Worth is 1664-64 = Rs.1600

Intrest on Present Worth(Rs.1600) is Rs.64

So Rate % is 64/1600 =4%

Rate % for 4months is 4% *12/4 = 12%

Simply given that sum due =Rs. 1664
TD=Rs.64
then PW=sum due-TD=1664-64=Rs.1600 ,t=4 months=1/3 year
then TD=(PW×R×T)/100
or,R=(TD×100)/PW×T
if we put all values in above formula then we will get R=12? Ans
Hence option (5) is the right answer.

Total Amount = Present worth + true discount
Simple Interest on (1664-64) for 4 months is 64
Rate % = (100*122)/(1600*(1/3)) = 12

Present Worth (PW)=1664-64 = 1600

S.I on 1600 for 4 month is Rs 64
convert month into year

Rate = (100 * SI)/P*N
=100 * 64/(1600 *4/12)
=100 * 64 * 3/1600
=12
rate percent is 12%

P.W=RS(1664-64)=RS.1600
S.I on RS.1600 for 4 months =RS. 64
therefore, rate =((100*64)/(1600*(1/3)))%=12%

option 5) i.e 12% is ans

Formula
T.D= (P.W*R*T)/100
=> R= {(100*T.D)/(P.W*T)}%
But
P.W= Rs. (1664-64)
=Rs.1600
And S.I on Rs. 1600 for 4months is Rs. 64
Therefore,
Rate = {(100*64)/(1600*4/12)}%
=(6400/533.333)%
=12.0000% ~
=12%
Hence Option 5). Is correct option

P.W = 1664-64= 1600
S.I on Rs 1600 for 4 months is 64
Rate= (100*64)/(1660*1/3)
Rate = 12%

OR we can use direct formula also of T.D
T.D= A*R*T/(100+(R*T))
T=4/12
So, 64= (1664*R*1/3) / (100+1/3 R)
R = 12%
Hence option 5 is correct

Discount (SI) = P×R×T = 64
P=1664-64= 1600
T=4/12=1/3
R=?
64 = 1600 × R × 1/3
R = 12%

As per question

P.w = 1664-64=1600

S.I on 1600 for 4 month is 64

so Rate is =(100*64*3)/(1600)=(64*3)/16=12

so option 5 is correct.
