If x, y, z are three sum of money such that y is the simple interest on x and z is the simple interset on y for the same time and at the same rate of interest, then we have
-
- z² = xy
- xyz = 1
- x² = yz
- y² = zx
- z² = xy
Correct Option: D
We know that ,
| SI = | |
| 100 |
| ∴ y = | |
| 100 |
| and z = | |
| 100 |
| So, | = | ⇒ y2 = zx | ||
| z | y |
