Answer:-

1.Sol:- (3) 




2.Sol:-

Let number be (x – 1) , x , (x + 1)
Now SSC-CGL-MATHS-QUIZ-15-12-2019
X = 30 
Required average = 30

3.Sol:- (1)

( s – t )  = 4   , s.t  =  21
After solving, s = 7, t =  3
SSC-CGL-MATHS-QUIZ-15-12-2019  = SSC-CGL-MATHS-QUIZ-15-12-2019

4.Sol:-

SSC-CGL-MATHS-QUIZ-15-12-2019
SSC-CGL-MATHS-QUIZ-15-12-2019
S = 4, t  = - 3 , u = 2
( t + u).s = (-3 + 2).4 = 4

5.Sol:- (4)

Let side be 10x
Area = 100x^2
New side = 10.3x
Area = 106.09x^2
Percentage change = SSC-CGL-MATHS-QUIZ-15-12-2019

6.Sol:- (2)

Alcohol                    Spirit              
( 8                             5)                                   
(8                            11)
6 ratio = 24 , 1 ratio =  4, total mixture = 13 x 4 = 52
Required answer = 13

7.Sol:-

ATQ,
SSC-CGL-MATHS-QUIZ-15-12-2019
(I – III)/2 = 67


8. Sol. (D)

The number must be divisible by 3 and four
Divisibility of 3 is -
SSC-CGL-MATHS-QUIZ-15-12-2019
X should be 2

9. Sol. (D)

8×5=(x+6)×x
x2+6x-40= 0
x= 4, – 10
x= 4

10. Sol. (B)
