A and B are two fixed points 5 cm apart and C is a point on AB such that AC is 3 cm. If the length of AC is increased by 6%, the length of CB is decreased by
-
- 6%
- 7%
- 8%
- 9%
Correct Option: D
Increase in AC = 6%
| ∴ Increased AC = | × 3 = 3.18 cm | 100 |
∴ Decreased CB = 5 – 3.18 = 1.82 cm.
∴ Decrease = 2 – 1.82 = 0.18 cm
∴ Percentage decrease
| = | × 100 = 9% | 2 |
