SOLUTIONS:

1.Option C
1/8 + 1/12 + 1/C = 1/4, we get C = 24 days
now efficiency of A, B and C are in the ratio of 1/8 :1/12 : 1/24
3:2:1, so share of C is 1/6 * 1200 = 200

2.Option B
Ages of Manju and her daughter = 6x, x
[6x + 1 + 6] – [x + 1 + 6] = 20
5x = 20; x = 4
Ratio = 6x + 1 : x + 1 = 25 : 5 = 5:1

3.Option D
P*(1 + 4/100)^8 = (3903 – P)*(1 + 4/100)^10
= 2028

4.Option C
Distance = time * [B^2 – R^2] / 2*B
Distance = 4* [4^2 –2^2] / 2*4
= 6 km

5.Option D
Probability = probability of selecting the bag and probability of selecting red ball
(1/2)*(3/11) + (1/2)*(5/12) = 91/264

6. B 7. A 8. D 9. C 10. E 11.Option D
4 × 1 + 2 = 4 + 2 = 6
6 × 2 + 3 = 12 + 3 = 15 == 18
15 × 3 + 4 = 45 + 4 = 49
49 × 4 + 5 = 196 + 5 = 201
201 × 5 + 6 = 1005 + 6 = 1011

12.Option C
48 ×3/2 = 72
72 ×3/2 = 108
108 × 3/2= 162
162 × 3/2 = 243
243 ×3/2 = 364.5 == 366

13.Option B
2 × 6 + 7 × 6 = 12 + 42 = 54
54 × 5 + 6 × 5 = 270 + 30 = 300
300 × 4 + 5 × 4 = 1200 + 20 = 1220
1220 × 3 + 4 × 3 = 3660 + 12
= 3672 == 3674
3672 × 2 + 3 × 2 = 7344 + 6 = 7350

14.Option B
2^3 = 8 : 3^3 = 27
4^3 = 64 : 5^3 = 125
6^3 = 216 == 218
7^3 = 343

15.Option C
19 + 7^2 = 19 + 49 = 68
68 + 6^2 = 68 + 36 = 104 == 102
104 + 5^2 = 104 + 25 = 129
129 + 4^2 = 129 + 16 = 145
145 + 3^2 = 145 + 9 = 154
