Simple Interest
A sum of Rs. 2600 is lent out in two parts in such a way that the interest on one part at 10% for 5 years is equal to that on another at 9% for 6 years. The sum lent out at 10% is:
| A. | 1150 |
| B. | 1250 |
| C. | 1350 |
| D. | 1450 |
| E. | None of these |

Let the sum lent at 10% be Rs. a and that lent at 9% be Rs. (2600 - a). Then,
a x 10 x 5
=
(2600 - a) x 9 x 6
100
100
=>
50a = (2600 x 54) - 54a
a =
2600 x
54
= 1350.
