years is Rs. 558 and the true discount on the same sum for 2 years is Rs. 600. The rate percent is:
Answer: Option
Explanation:
B.D. for  years |
= Rs. 558. | |||||||
| B.D. for 2 years |
|
|||||||
| = Rs. 744 |
T.D. for 2 years = Rs. 600.
 Sum = |
B.D. x T.D. | = Rs. |  |
744 x 600 |  |
= Rs. 3100. |
| B.D. - T.D | 144 |
Thus, Rs. 744 is S.I. on Rs. 3100 for 2 years.
| Rate = |
|
100 x 744 | % |
= 12% |
| 3100 x 2 |

B.D = A*r*t1/100 ---> (1) and
T.D. = A*r*t2/(100+rt2) ---> (2).
Now as the amount or sum of money is same so from (1) A= B.D*100/(r*t1).
From (2) A= T.D*(100+r*t2)/(r*t2).
Put values and compare both as 'A' is same.
558*100/(r*3/2) = 600*(100+2r)/(2r).
55800*2/3 = 300(100+2r).
On solving
1860 = 1500 + 30r.
r = 360/30.
r = 12% answer.

1*1/2 = 18months.
2 = 24months,
18m = 558rs,
24m = ?
1m = 31rs.
24m = 744rs.
T.D. for 2 years = Rs. 600.
Sum = B.D. x T.D.
= Rs. 744 x 600,
= Rs. 3100.
B.D. - T.D 144
Thus, Rs. 744 is S.I. on Rs. 3100 for 2 years.
Rate = 100 x 744%.
= 12%
2 = 24months,
18m = 558rs,
24m = ?
1m = 31rs.
24m = 744rs.
T.D. for 2 years = Rs. 600.
Sum = B.D. x T.D.
= Rs. 744 x 600,
= Rs. 3100.
B.D. - T.D 144
Thus, Rs. 744 is S.I. on Rs. 3100 for 2 years.
Rate = 100 x 744%.
= 12%

@Nandini.
Let x = No of males, y = No of female.
x+y = 9000.
As males increased by 5% no of males become 1.05*x, female becomes 1.08*y there for 1.
05x+1.08y = 9600 by solving the above two equations you will get the answer.

Given banker's discount(b.d) for 3/2 yrs = 558
then banker's discount(b.d) for 2 yrs = x
x=(558*2)/(3/2)
x=744
we know
t.d=(b.d*100)/(100+(r*t))
600=(744*100)/(100+(r*2))
Therefore, r=12%
then banker's discount(b.d) for 2 yrs = x
x=(558*2)/(3/2)
x=744
we know
t.d=(b.d*100)/(100+(r*t))
600=(744*100)/(100+(r*2))
Therefore, r=12%

let the present worth be x then BD for 18 months will be;
x(1+3R/100)*3R/100= 558------------->(i)
TD for 2 years.
xR*2/100 = 600----------------> (ii)
Dividing (i)/(ii).
Will get R = 16.
x(1+3R/100)*3R/100= 558------------->(i)
TD for 2 years.
xR*2/100 = 600----------------> (ii)
Dividing (i)/(ii).
Will get R = 16.

Why we can't calculate T.D for 3/2 years = Rs 450.
B.D=558, T.D=450.
So, Sum=B.DX T.D/(B.D-T.D),
If we calculate, it comes out R=16% per annum.
Please, tell me where is the mistake?

FOR TWO YEARS THE BD IS:
588 * (2/3) * 2 = 784. (not 744).
The final answer comes out to be 16.6667.
588 * (2/3) * 2 = 784. (not 744).
The final answer comes out to be 16.6667.
