If the angles of a triangle are in the ratio 1 : 2 : 3, then what is the smallest angle?

  1. 15°
  2. 25°
  3. 30°
  4. 40°
Show answer and solution

Correct answer: C. 30°

1. Let the angles be x, 2x and 3x. 2. Their sum is 180°: x + 2x + 3x = 6x = 180°. 3. So x = 30°. 4. The smallest angle is x = 30°. _Source: RRB Group D CEN-02/2018 PYQ, Q.15._
