Answers :
Directions (1-5) :
1) Answer: A
Series I,
12 * 2.5 = 30
30 * 2.5 = 75
75 * 2.5 = 187.5
187.5 * 2.5 = 468.75
Series II,
2 is the 1st term
2 * 2.5 = 5
5 * 2.5 = 12.5
12.5 * 2.5 = 31.25
31.25 * 2.5 = 78.125
78.125 is the 5th term
2) Answer: B
Series I,
8640/6 = 1440
1440 / 5 = 288
288 / 4 = 72
72 / 3 = 24
Series II,
1560 is the 1st term
1560 / 6 = 260
260 / 5 = 52
52 / 4 = 13
13 is the 4th term
3) Answer: A
Series I,
25 * 1 + 1 = 26
26 * 2 + 2 = 54
54 * 3 + 3 = 165
165 * 4 + 4 = 664
664 * 5 + 5 = 3325
Series II,
7 is the 1st term
7 * 1 + 1 = 8
8 * 2 + 2 = 18
18 * 3 + 3 = 57
57 is the 4th term.
4) Answer: C
Series I,
14 * 3 + 10 = 52
52 * 2.5 + 10 = 140
140 * 2 + 10 = 290
290 * 1.5 + 10 = 445
Series II,
2 is the 1st term.
2 * 3 + 10 = 16
16 * 2.5 + 10 = 50
50 * 2 + 10 = 110
110 * 1.5 + 10 = 175
175 is 5th term.
5) Answer: D
Series I,
8 + 132Â = 177
177 + 112Â = 298
298 + 92Â = 379
379 + 72Â = 428
428 + 52Â = 453
Series II,
11 is 1st term.
11 + 132Â = 180
180 + 112Â = 301
301 is 3rd term.
Directions (6-10) :
6) Answer: B
Speed of the stream = x
Time taken in upstream = 120/(20 – x) = 8
(20 – x) * 8 = 120
20 – x = 15
x = 5 kmph
Time taken in downstream = 8 – 2 = 6 hours
D/(20 + 5) = 6
D = 150 km
7) Answer: C
(160/(30 + x))/(120/(30 – x)) = 2/3
4 * (30 –x)/[3 * (30 + x)] = 2/3
60 – 2x = 30 + x
3x = 30
x = 10 kmph
8) Answer: C
Speed of the stream on day3 = x
Speed of stream on day4 = y
200/(25 + x) = 5
40 = 25 + x
x = 15 kmph
240/(40 + y) = 4
60 = 40 + y
y = 20 kmph
Distance travelled in upstream on day3 = (25 – 15) * 5 = 50 km
Distance travelled in upstream on day4 = (40 – 20) * 4 = 80 km
Required sum = 50 + 80 = 130 km
9) Answer: A
Time taken by boat in upstream = 80/(25 – 5) = 4 hours
Time taken by boat travelled in downstream = 3 hours
Distance travelled by boat in downstream = 3 * (25 + 5) = 90 km
Required difference = 90 – 80 = 10 km
10) Answer: B
Speed of the stream on day2= x
Time taken in downstream on day2 = 2 hours
80/(30 + x) = 2
60 + 2x = 80
2x = 20
x = 10 kmph
Time taken in upstream on day2 = 3 hours
Distance travelled in upstream on day2 = 3 * (30 – 10) = 60 km
Distance travelled in downstream on day3 = 60 + 30 = 90km
Distance travelled in upstream on day2 = 60 km
Required ratio = 60:90 = 2:3
