**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 ,KVS,STET Exam.**

SOLUTIONS

S1. Ans.(d)

Sol

Revenue for 6th year = (6 × 72) + (6 × 84) – (11 × 77) = 89 lakh

S2. Ans. (c)

Sol.

Let the third proportion be ‘x’.

ATQ,

12/48=48/x

x = (48×48)/12

x = 192

S3. Ans.(c)

Sol.

Let the present ages of Rangitha and Shaheen be 6x and 5x respectively.

(6x+12)/(5x + 12) = 7/6

36x + 72 = 35x + 84

X = 12

Rangitha’s present age = 6 ×12 = 72 years

S4. Ans.(d)

Sol.

Let the angle be ‘θ’.

ATQ,

θ = (180° – θ) – 50

2θ = 130°

θ = 65°

S5. Ans.(c)

Sol.

In a Rhombus, sum of adjacent angles is 180°. Hence, consecutive angles are supplementary.

S6. Ans.(d)

Sol.

⇒ (x + 11) (3 – 5x)

⇒ 3x – 5x² + 33 – 55x

⇒ -5x² – 52x + 33

Coefficient of x =-52

S7. Ans.(b)

Sol. Total surface area of cube = 6a²

Where ‘a’ is the side of the cube

Now, 6a² = 24

⇒a^2=24/6=4⇒a=2

Volume of cube = a³ = 2³ = 8 cm³

S8. Ans.(b)

Sol. We know that

Number1 × Number2 = LCM × HCF

∴LCM=(63×77)/7=693

S9. Ans.(d)

Sol.

Let the marks scored by two candidates be x & (x + 10)

ATQ

(x + 10) =75/100 (x+x+10)

⇒ 4x + 40 = 6x + 30

x = 5

∴ the marks scored are 5 & 15.

S10. Ans.(a)

Sol.

3565/1495=(5×23×31)/(5×23×13)=31/13
