ANSWERS:

1. Sol. (A) 
Let Rakesh's share = Rs.x
and Anil's share = Rs. (21594 – x) 
According to the question,
http://onlinespeedtest.mahendras.org/Images/148467105988467.jpg 

2. Sol. (C) 
tan 30o = maths-ssc-quiz-04-10-19
maths-ssc-quiz-04-10-19
h = maths-ssc-quiz-04-10-19 m.


3. Sol. (D) 
According to the question,
maths-ssc-quiz-04-10-19
(21 + n) × 3 = (35 + n) × 2
63 + 3n = 70 + 2n
n = 7


4. Sol. (D)p: q: r = 2: 3: 5
Hence, p = 2x, q = 3x and r = 5x
p + q + r = 80
2x + 3x + 5x = 80
10x = 80, x = 8
p = 16, q = 24 and/और r = 40
From the given equation,
40 = m × 16 – 8
m = 3  


5. Sol. (B)Ayushi + Aanchal …… 12                                                5 units of work per day
                                                     [L.C.M. of 12 and 15 = 60]
Aanchal + Vaishnavi ……15                                             4 units of work per day
According to the question,
Ratio between efficiency of Ayushi and Vaishnavi = 2: 1
Ayushi + Aanchal + Aanchal + Vaishnavi = 5 + 4
2 + 2 × Aanchal + 1 = 9
Aanchal = 3
Time taken by Aanchal to complete the work = 60 ÷ 3 = 20 days


6. Sol. (D) (x – 2) (x – p) = x2 – ax + 6
x2 – px – 2x + 2p = x2 – ax + 6
x2 – (p + 2) + 2p = x2 – ax + 6
On comparison both the sides, we get
p + 2 = a, 2p = 6
p + 2 = a, p = 3
3 + 2 = a, a = 5
Now, a – p = 5 – 3 = 2


7. Sol. (C) http://onlinespeedtest.mahendras.org/Images/152336495283444.jpg
On solving above, we get
r = 20%


8. Sol. (B) Product of the numbers = 24
xy = 24 ........ (I)
Difference of the numbers = 2
x – y = 2 ....... (II)
From (I) and (II), we get,
x = 6, y = 4
Required answer = 62 + 42 = 36 + 16 = 52


9. Sol. (A) Case – I:
S.P: C.P. = 4: 5 = 16: 20
Case – II:
S.P: C.P. = 5: 4 = 25: 20
According to the question,
25 – 16 = 108
9 = 108
20 = 240


10. Sol. (B) Let side of the square = a cm.
Breadth of the rectangle = (a – 3) cm.
Length of the rectangle = (a + 5) cm.
According to the question,
a2 = l
a2 = (a – 3) (a + 5) 
a2 = a2 + 2a – 15 
a = 15/2 = 7.5 cm.
Perimeter of the rectangle = 2 (l + b) 
= 2 (4.5 + 12.5) = 34 cm.
