					 The ratio of the angles of a triangle is 1 : 2 : 3 .Then the smallest angle is : 3 
- 
                        -  21 4° 7 
- 25°
-  25 5° 7 
-  38 4° 7

Correct Option: C
As per the given in question, 
In a ∆ ABC,
| ∠A : ∠B : ∠C = 1 : | : 3 = 3 : 2 : 9 | |
| 3 | 
Sum of the terms of ratio = 3 + 2 + 9 = 14
| ∴ Lowest angle = ∠B = | × 180° | |
| 14 | 
| Lowest angle = ∠B = | = 25 | ||
| 7 | 7 |
