Answer Key:

1. Sol. (B) 


Single equivalent discount for successive discounts of 30% and 20%/30% और 20% की क्रमागत छूटों के समतुल्य एकल छूट
= ssc-math-quiz-15-09-19= 44%
Single equivalent discount for successive discounts of 44% and 10%/44% और 10% की क्रमागत छूटों के समतुल्य एकल छूट
= ssc-math-quiz-15-09-19= 49.60%

2. Sol. (D) 

Req. Remainder/ अभीष्ट शेषफल = ssc-math-quiz-15-09-19
= ssc-math-quiz-15-09-19
= ssc-math-quiz-15-09-19= 1

3. Sol. (C) 

Third number/ तीसरी संख्या = 5 × 371.8 – 2 × 256.5 – 2 × 508
 = 1859 – 513 – 1016 = 1859 – 1529
 = 330

4. Sol. (C)

5. Sol. (D) 

A                                 B
70                                100
Required/ अभीष्ट % = ssc-math-quiz-15-09-19 = 42.85%

6. Sol. (B)


Required probability/ अभीष्ट प्रायिकता = ssc-math-quiz-15-09-19

7. Sol. (C) 

R = ssc-math-quiz-15-09-19
= 10%
P = ssc-math-quiz-15-09-19= Rs. / रू.900

8. Sol. (B) 

sin θ + cos θ = ssc-math-quiz-15-09-19
sin θ. cos θ = ssc-math-quiz-15-09-19
sin2 θ + cos2 θ = ssc-math-quiz-15-09-19
b2 – 2ac = a2
a2 – b2 + 2ac = 0

9. Sol. (C) 

Let number of ladies who did not report for the work be x.
माना महिलाओं की संख्या जो काम पर नहीं आ सकीं, x है ।
(76 – x) × 44 = 76 × 33
44x = 76 × 44 – 76 × 33
x = ssc-math-quiz-15-09-19
x = 19

10. Sol. (D) 

Let fourth proportional be x. / माना चौथा समानुपातिक x है ।
7: 11 :: 14: x
7 × x = 11 × 14
x = 22
