(A) 8
(B) 10
(C) 12
(D) 5

Answer key:

1. Sol. (C) 


On dividing 6729 by 35, we get remainder/6729 рдХो 35 рд╕े рднाрдЧ рдХрд░рдиे рдкрд░, рд╣рдо рд╢ेрд╖рдлрд▓ рдк्рд░ाрдк्рдд рдХрд░рддे рд╣ैं = 9


2. Sol. (B) 


ssc-26
According to the question/ рдк्рд░рд╢्рдиाрдиुрд╕ाрд░,
6 × 1 + 1 × n = 60
n = 60 – 6 = 54


3. Sol. (A) 


2 (l + b) × h = 448
2 (18 + b) × 8 = 448
18 + b = 28
b = 10


4. Sol. (B) 


90% = Rs.4500
100% = Rs.5000
72.5% = Rs. 3625


5. Sol. (C) 


72: 168:: 150: x
72 × x = 168 × 150
x = ssc-26= 350


6. Sol. (A) 


(p + q + r)2 = p2 + q2 + r2 + 2 (pq + qr + rp)
361 = 133 + 2 (pq + qr + q2)
114 = q (p + q + r)
q = 6
Now/ рдЕрдм, p + r = 13 and/ рдФрд░ p2 + r2 = 97
Again/ рдкुрдиः,
(p – r)2 = p2 + r2 – 2 rp
(p – r)2 = 97 – 2 × 36
(p – r)2 = 25
p – r = 5


7. Sol. (D) 


Using the method of alligation/ рдоिрд╢्рд░рдг рдХे рдиिрдпрдо рд╕े,
ssc-26
Required ratio/ рдЕрднीрд╖्рдЯ рдЕрдиुрдкाрдд = 1: 2
Required quantity sold at 8% profit/8% рд▓ाрдн рдкрд░ рдмेрдЪीं рдЬाрдиे рд╡ाрд▓ी рдЕрднीрд╖्рдЯ рдоाрдд्рд░ा = ssc-26
= 640 kgs/ рдХिрдЧ्рд░ा



8. Sol. (B) 


4 – 2 sin2 q – 5 cos q = 0
4 – 2 (1 – cos2 q) – 5 cos q = 0
4 – 2 + 2 cos2 q – 5 cos q = 0
2 cos2 q – 5 cos q + 2 = 0
2 cos2 q – 4 cos q – cos q + 2 = 0
2 cos (cos q – 2) – 1 (cos q – 2) = 0
(cos q – 2) (2 cos q – 1) = 0
cos q = 2, ½
q = 60o
sin q + tan q = sin 60o + tan 60o
= ssc-26= ssc-26= ssc-26


9. Sol. (D)
Required minutes/ рдЕрднीрд╖्рдЯ рдоिрдирдЯ = ssc-26= 10 


10. Sol. (B) 


Simple interest for two years/2 рд╡рд░्рд╖ों рдХे рд▓िрдП рд╕ाрдзाрд░рдг рдм्рдпाрдЬ = Rs. / рд░ु. 1500
Simple interest for one year/1 рд╡рд░्рд╖ рдХे рд▓िрдП рд╕ाрдзाрд░рдг рдм्рдпाрдЬ = Rs. / рд░ु. 750
Simple interest for first year/ рдкрд╣рд▓े рд╡рд░्рд╖ рдХे рд▓िрдП рд╕ाрдзाрд░рдг рдм्рдпाрдЬ
= Compound interest for first year/ рдкрд╣рд▓े рд╡рд░्рд╖ рдХे рд▓िрдП рдЪрдХ्рд░рд╡ृрдж्рдзि рдм्рдпाрдЬ
Compound interest for second year/ рджूрд╕рд░े рд╡рд░्рд╖ рдХे рд▓िрдП рдЪрдХ्рд░рд╡ृрдж्рдзि рдм्рдпाрдЬ = 1575 – 750 = Rs. / рд░ु. 825
R = ssc-26= 10%
