Solutions:

1. Sol. (D)

рджिрдпे рдЧрдП рдк्рд░ेрдХ्рд╖рдгों рдХो рдЖрд░ोрд╣ी рдХ्рд░рдо рдоें рд╡्рдпрд╡рд╕्рдеिрдд рдХрд░рдиे рдкрд░


5, 12, 32, 34, 51, 57, 57, 62, 62, 67, 92, 97


n = 12


рдЕрддः, рдоाрдз्рдпिрдХा = ½ [6рд╡ाँ рдкрдж + 7рд╡ाँ рдкрдж] = 572. 

2.Sol. (B) 
Men              15: 20
                                                     :: 10: x
Hours            8: 7
According to the question,
15 × 8 × x = 20 × 7 × 10
x = ssc-maths-quiz-15-10-19 days


3. Sol. (A) 
M – 7 = 7 (S – 7)
M – 7S = – 42 … (i)
M + 3 = 3 (S + 3)
M – 3S = 6 … (ii)
From (i) and (ii), we get
M = 42, S = 12


4. Sol. (D) 
рддीрд╕рд░े рд╡िрд╖рдп рдоें рдЕंрдХ = 5 × 75 – 2 × 65 – 2 × 85
= 375 – 130 – 170
= 75


5. Sol. (B) 
According to the question,
ssc-maths-quiz-15-10-19
ssc-maths-quiz-15-10-19
a = 8 ssc-maths-quiz-15-10-19
Area of the equilateral triangle = ssc-maths-quiz-15-10-19ssc-maths-quiz-15-10-19 sq. unit 


6. Sol. (C) 
x (x + a) (x + 2a) (x + 3a) + a4 = (x2 + a2 + 3ax)2
Hence, Term to be added = a4


7. Sol. (B)
cos 2580o = cos (2520o + 60o)
= cos(7 × 360o + 60o)
= cos 60o = ssc-maths-quiz-15-10-19  


8. Sol. (A) 
40% of 20% + 30% of 25% + 50% of 28%
= 8% + 7.5% + 14% = 29.5%


9. Sol. (A) 
(a3 + b3 + c3 – 3abc) = [(a + b + c)2 – 3 (ab + bc + ca)]
(a3 + b3 + c3 – 3ab) = = 13 × [(13)2 – 3 × 25]
= 13 × 94 = 1222 


10. Sol. (C) 
Let speed of the boat in still water be x km. /hr.
According to the question,
ssc-maths-quiz-15-10-19
12 x = 2(x2 – 16)
12 x = 2x2 – 32
2x2 – 12x – 32 = 0 
x2 – 6x – 16 = 0
x2 – 8x + 2x – 16 = 0
x (x – 8) + 2(x – 8) = 0 
(x – 8) (x + 2) = 0
x = 8, – 2
Speed of the boat in still water = 8 km./hr.
