(A) 10

(B) 25

(C) 36

(D) 40

Answer Key:

1. Sol. (D) 

Interest obtained from scheme A/рдпोрдЬрдиा A рд╕े рдк्рд░ाрдк्рдд рдм्рдпाрдЬ = (24000 × 10 × 2)/ 100 = 480
Interest obtained from scheme B/рдпोрдЬрдиा A рд╕े рдк्рд░ाрдк्рдд рдм्рдпाрдЬ = (2400 – x) [{1 + (15/100)}2 – 1]
= (2400 – x) × (129/400)
According to the question/рдк्рд░рд╢्рдиाрдиुрд╕ाрд░,
(2400 – x) × (129/400) – 480 = 165
(2400 – x) × (129/400) = 480 + 165 = 645
(2400 – x) = 645 × (400/129)
x = 400

2. Sol. (A) 

Average weight of the girls/рд▓реЬрдХिрдпों рдХा рдФрд╕рдд рднाрд░ = x
Average weight of the boys/рд▓реЬрдХों рдХा рдФрд╕рдд рднाрд░ = x – 2
Total weight of the girls/рд▓реЬрдХिрдпों рдХा рдХुрд▓ рднाрд░ = 20x
Total weight of the boys/рд▓реЬрдХों рдХा рдХुрд▓ рднाрд░ = 15(x – 2)
According to the question/рдк्рд░рд╢्рдиाрдиुрд╕ाрд░,
20x = 15(x – 2) + 190
20x – 15x = 160
5x = 160
x = 32
Average weight of the class/рдХрдХ्рд╖ा рдХा рдФрд╕рдд рднाрд░ = [(15 × 30 + 20 × 32)/ 35] = 31.7 (approx.)

3. Sol. (C) 

Let first and second part of the number be x and y respectively.
рдоाрдиा рдкрд╣рд▓ी рдФрд░ рджूрд╕рд░ी рд╕ंрдЦ्рдпा рдХ्рд░рдорд╢ः x рдФрд░ y рд╣ैं ।
80% of x/x рдХा 80% = 60% of y/y рдХा 60% + 3 ……… (I)
and/рдФрд░ 90% of x/x рдХा 90% + 6 = 80% of y/y рдХा 80% ……….. (II)
On solving (I) and (II), we get/(I) рдФрд░ (II) рдХो рд╣рд▓ рдХрд░рдиे рдкрд░,
x = 60, y = 75
Required answer/рдЕрднीрд╖्рдЯ рдЙрдд्рддрд░ = 111 × 135 = 14985

4. Sol. (A) 

According to the question/рдк्рд░рд╢्рдиाрдиुрд╕ाрд░,
(750 + 750)/ 300 = (s1 – s2) … (I)
(750 + 750)/ 60 = (s1 + s2) … (II)
On solving (I) and (II), we get/ (I) рдФрд░ (II) рдХो рд╣рд▓ рдХрд░рдиे рдкрд░,
s1 = 36 km/hr. /рдХिрдоी./рдШंрдЯा, s2 = 54 km/hr. /рдХिрдоी./рдШंрдЯा

5. Sol. (D) 

According to the question/рдк्рд░рд╢्рдиाрдиुрд╕ाрд░,
(30/ U) + (45/ D) = 6 … (i)
(45/ U) + (30/ D) = 6.5 … (ii)
On solving (i) and (ii), we get/ (i) рдФрд░ (ii) рдХो рд╣рд▓ рдХрд░рдиे рдкрд░,
D = 15, U = 10
Speed of man in still water/рд╕्рдеिрд░ рдЬрд▓ рдоें рд╡्рдпрдХ्рддि рдХी рдЪाрд▓ = 12.5 km/hr. /рдХिрдоी./рдШंрдЯा

6. Sol. (B) 

A …… 28 5
140
B ……. 35 4
According to the question/рдк्рд░рд╢्рдиाрдиुрд╕ाрд░,
9 × x + 4 × 17 = 140
9x = 140 – 68 = 72
x = 8 days/рджिрди

7. Sol. (B) 

S.I. in three years/рддीрди рд╡рд░्рд╖ рдоें рд╕ाрдзाрд░рдг рдм्рдпाрдЬ = [{20000 × (5 + 4 + 2) × 1}/ 100] = 2200
C.I. in three years/рддीрди рд╡рд░्рд╖ рдоें рдЪрдХ्рд░рд╡ृрдж्рдзि рдм्рдпाрдЬ = [{20000 × (105/100) × (104/100) × (102/100)} – 20000] = 2276.8
Required difference/рдЕрднीрд╖्рдЯ рдЕрди्рддрд░ = 2276.8 – 2200 = Rs.76.8

8. Sol. (B) 

4 M = 6 W
2 M = 3 W
10 M + 3 W = 15 W + 3 W = 18 W
Let number of days taken by 10 men and 3 women to complete the double of the work is D.
рдоाрдиा 10 рдкुрд░ुрд╖ рдФрд░ 3 рдорд╣िрд▓ाрдУं рдж्рд╡ाрд░ा рдЗрд╕ рдХाрд░्рдп рдХे рджोрдЧुрдиे рдХाрд░्рдп рдХो рдкूрд░ा рдХрд░рдиे рдоें рд▓िрдП рдЧрдП рджिрдиों рдХी рд╕ंрдЦ्рдпा D рд╣ै
According to the question/рдк्рд░рд╢्рдиाрдиुрд╕ाрд░,
2 × 6 × 7 × 12 = D × 8 × 18
D = 7

9. Sol. (B) 

Equivalent ratio between capitals/рд╕рдорддुрд▓्рдп рдкूंрдЬिрдпों рдоें рдЕрдиुрдкाрдд
= 10000 × 8: 6000 × 12
= 10: 9
Q's share/Q рдХा рд╣िрд╕्рд╕ा = (9/19) × 5700 = Rs. /рд░ु. 2700



10. Sol. (B) 

L.C.M. of 10, 12 and 25/10, 12 рдФрд░ 25 рдХा рд▓.рд╕.рдк. = 300
Smallest perfect square/рд╕рдмрд╕े рдЫोрдЯा рдкूрд░्рдг рд╡рд░्рдЧ = 300 × 3 = 900
which is divisible by 10, 12 and 25/рдЬोрдХि 10, 12 рдФрд░ 25 рд╕े рд╡िрднाрдЬिрдд рд╣ै |
So/рдЕрддः, required answer/рдЕрднीрд╖्рдЯ рдЙрдд्рддрд░ = 900/36 = 25
