Answer:-

1.Sol:-  (3)
SSC-CGL-MATHS-28-01-2020
PA x AQ = AM x AD

10 x 16 = AM x (AM + 12)
SSC-CGL-MATHS-28-01-2020
On Solving,
AM = 8, -20
(x = 8 + 6) = 14cm


2. Sol:- (3)

SSC-CGL-MATHS-28-01-2020
After solving SSC-CGL-MATHS-28-01-2020
SSC-CGL-MATHS-28-01-2020 = SSC-CGL-MATHS-28-01-2020


3. Sol:- (3)

= SSC-CGL-MATHS-28-01-2020
Second interest x = SSC-CGL-MATHS-28-01-2020


4. Sol:- (4)

SSC-CGL-MATHS-28-01-2020
= 10 (100 – 75) +  3 x 100 = 550


5. Sol:- (4)

SSC-CGL-MATHS-28-01-2020
SSC-CGL-MATHS-28-01-2020 

SSC-CGL-MATHS-28-01-2020
90 unit = 648
1 unit = 7.2
116 unit = Rs. 835.2


6. Sol. (2)

SSC-CGL-MATHS-28-01-2020
PA.PB=PD.PC
SSC-CGL-MATHS-28-01-2020


6. हल. (2)

SSC-CGL-MATHS-28-01-2020
PA.PB=PD.PC
SSC-CGL-MATHS-28-01-2020


7. Sol. (2)

8.हल. (1)

SSC-CGL-MATHS-28-01-2020

9. Sol. (4)

SSC-CGL-MATHS-28-01-2020Km/hr
U-V = 5 km/hr
SSC-CGL-MATHS-28-01-2020km/hr


9. हल. (4)

SSC-CGL-MATHS-28-01-2020किमी/घंटा
U-V = 5 किमी/घंटा
SSC-CGL-MATHS-28-01-2020किमी/घंटा


10. Sol. (1)

Total = 100
Male = 60, female = 40
Married (male= 30, female = 28)
Unmarried (male = 30, female = 12)
Required percentage = 42%


10. हल. (1)

कुल = 100
पुरुष = 60, महिला = 40
विवाहित (पुरुष= 30, महिला = 28)
अविवाहित (पुरुष = 30, महिला = 12)
