# Maths Questions for DSSSB Exam : 2nd August 2018 (Solutions)

Dear Students!!! There is most general as well as a scoring section in all the competitive entrance examinations in the teaching field i.e “Mathematics”.Because in this section only one thing is work i.e your accuracy and that could be nourished with the daily practice. So, for this, we are providing you the daily quiz for all teaching exams i.e CTET Exam 2018, DSSSB Exam & STET Exam.

(a) ∆ABC ≅ ∆DEF
(b) ∆ABC ≅ ∆EDF
(c) ∆ABC ≅ ∆FED
(d) ∆ABC ≅ ∆FDE
Q8. In ∆ABC and ∆LMN, AB = LM, AC = LN and ∠B = ∠M. Then the
(a) triangles cannot be congruent
(b) triangles must be congruent
(c) triangles will be congruent if ∠B is a right angle

(a) 45°
(b) 90°
(c) 135°
(d) 180°
Q10. The number of vertices in a polyhedron which has 30 edges and 12 faces is
(a) 12
(b) 15
(c) 20
(d) 24
Solutions
S1. Ans.(c)
Sol. Two angles are complementary if they add up to 90 degrees.
72° + 18° = 90°

S2. Ans.(c)
Sol. 60° + x = 145° (the exterior angle theorem)
⇒ x = 145° – 60° = 85°
