= 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.

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?

@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.
