CTET Scoring Mathematics Questions | Important Study Material


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 2019DSSSB ,KVS,STET Exam.

(a) 8
(b) 10
(c) 9
(d) 14

(a) x – y + 1
(b) x + y – 1
(c) x – y – 1
(d) x + y + 1

Q10. A man covers 9/20  by bus and the remaining 10 km on foot. His total journey (in km) is 
(a) 15.6
(b) 24
(c) 18.18
(d) 12.8

Solutions:

S1. Ans.(a)
Sol. Given expression can be written as
0.46² + 0.54² + 2 × 0.46 × 0.54
= (0.46 + 0.54)² = 1

S2. Ans.(c)
Sol. 17.28 ÷ ? = 2 × 3.6 × 0.2
i.e., 17.28/? = 1.44 = 1.2²
⇒(1.728×10)/?= (1.2)²
⇒[(1.2)³×10]/?=(1.2)²
⇒ ? = 12

S3. Ans.(a)
Sol. 3x – 15 = 120 ⇒ x = 45

S4. Ans.(c)
Sol. Volume of new sphere
=4/3 π(3³+4³+5³)
=4/3 π(27+64+125)
=4/3 π(216)=4/3 π6³
∴ Radius = 6

S5. Ans.(b)
Sol. 

A rhombus has two lines of symmetry joining its opposite vertices.

S7. Ans.(d)
Sol. Required area
=√3/4 a²=√3/4×(16)²=64√3  cm².

S8. Ans.(a)
Sol. Arrange the data in ascending order 1, 3, 5, 6, 7, 8, 9, 10, 12, 13, 14
Median = Middle observation = 8

S9. Ans.(c)
Sol. x² – 2xy + y² – x + y = (x – y)² – (x – y)
= (x – y) (x – y – 1)

S10. Ans.(c)
Sol. Total distance = D
11D/20=10
11D = 200
D=200/11
D = 18.18
