Answer key:

1. Sol. (A)
x = ssc--math-quiz-18-09-19
ssc--math-quiz-18-09-19=ssc--math-quiz-18-09-19× ssc--math-quiz-18-09-19
= ssc--math-quiz-18-09-19
= ssc--math-quiz-18-09-19
= ssc--math-quiz-18-09-19
= ssc--math-quiz-18-09-19 


2. Sol. (D) 


18x = 20 (x – 6)
18x = 20 x – 120
2x = 120
x = 60


3. Sol. (A) 


Required % decrease be x. /рдЕрднीрд╖्рдЯ рдк्рд░рддिрд╢рдд рдХрдоी x рд╣ै ।
10 – x – ssc--math-quiz-18-09-19= 0
x = ssc--math-quiz-18-09-19 


4. Sol. (C) 


5% = 500
100% = 10000 


5. Sol. (C)

6. Sol. (B) 


Unit digit in 34/34 рдоें рдЗрдХाрдИ рдХा рдЕंрдХ = 1
= (34)16 = 1
= 365 = 3
Similarly/рдЗрд╕ी рдк्рд░рдХाрд░ рд╕े, 659 = 6
74 = 1
(74)11 = 1
771 = (74)11 × 73 = 3
Unit digit/рдЗрдХाрдИ рдХा рдЕंрдХ = 3 × 6 × 3 = 4 


7. Sol. (C) 


http://onlinespeedtest.mahendras.org/Images/138120664970515.jpg 


8. Sol. (D) 


Required ratio/рдЕрднीрд╖्рдЯ рдЕрдиुрдкाрдд = (12.5 – 2.5 + 4) : (7.5 – 1.5)

= 14 : 6 = 7 : 3 

9. Sol. (D)
Reg. Average/рдЕрднीрд╖्рдЯ рдФрд╕рдд = ssc--math-quiz-18-09-19
= ssc--math-quiz-18-09-19
 = 115 cm. /рд╕ेрдоी. 


10. Sol. (D) 


Relative speed/рд╕ाрдкेрдХ्рд╖ рдЪाрд▓ = 36 + 45 = 81 km/hr. /рдХिрдоी. /рдШंрдЯा
 = ssc--math-quiz-18-09-19 = 22.5 m/s. /рдоी. /рд╕े.
ssc--math-quiz-18-09-19
200 + X = 450
X = 250 m. / рдоी.
