**Directions(1-5):** Find the missing term “?” of the following series.

- 15, 9, 8, ?, 36, 170
2018121521Option C

15 × 1 – 1 × 6 = 15 – 6 = 9

9 × 2 – 2 × 5 = 18 – 10 = 8

8 × 3 – 3 × 4 = 24 – 12 = 12

12 × 4 – 4 × 3 = 48 – 12 = 36

36 × 5 – 5 × 2 = 180 – 10 = 170 - 5, 9, 25, 91, ?, 2282.5
414302382400411Option A

5 × 1.5 + 1.5 = 7.5 + 1.5 = 9

9 × 2.5 + 2.5 = 22.5 + 2.5 = 25

25 × 3.5 + 3.5 = 87.5 + 3.5 = 91

91 × 4.5 + 4.5 = 409.5 + 4.5 = 414 - 7, ?, 10, 27, 104, 515
1285106Option E

7 × 1 – 1 = 6

6 × 2 – 2 = 10

10 × 3 – 3 = 27

27 × 4 – 4 = 104

104 × 5 – 5 = 515 - 8, 9, ?, 63, 256, 1285
3020105040Option B

8 × 1 + 1 = 9

9 × 2 + 2 = 20

20 × 3 + 3 = 63

63 × 4 + 4 = 256 - 6, 16, ?, 244, 1245, 7506
5944425750Option D

6 × 2 + 22 = 12 + 4 = 16

16 × 3 + 32 = 48 + 9 = 57

57 × 4 + 42 = 228 + 16 = 244 - The simple interest on a certain sum of money for 2 yr at 8% per annum is 30 less than the simple interest on the same sum for 3 yr at 6% per annum. Find the sum in Rs.
15001000112014501223Option A

T1 = 2

R1 = 8%

T2 = 3 yr and R2 = 6%

Let the sum be P. Then, P × 6 × 3/ 100 − P × 8 ×2/ 100 = 30

=> 18P/ 100 – 16P/ 100 = 30

P = Rs. 1500 - While selling a watch, a shopkeeper gives a discount of 5%. If he gives a discount of 6% he earns Rs. 15 less as profit. What is the marked price of watch ?
Rs. 1700Rs. 1000Rs. 1300Rs. 1500Rs. 1100Option D

Let the marked price be Rs.x

Then, 95x/100 – 94x/100 = 15

= Rs. 1500 - A train 108 metre long is moving at a speed of 50 km/hr. It crosses a train 112 metre long coming from opposite direction in 66 seconds. What is the speed of the second train?
7077868272Option D

Distance covered = (108+112) = 220 metre

Time = 6 seconds

Relative speed = 220/6 = 110/3 m/s

= 110/3 × 18/5 = 132 km/hr.

Speed of second train = (132−50) = 82 km/hr - A complete 4/5 part of a work in 20 days. Then he completes the rest work with B in 3 days. How much time will B take alone to complete this work ?
30(1/3) days37(1/2) days33(1/7) days40(1/2) days31(1/3) daysOption B

Days taken by A to complete the work

= 20 * 5/4 = 25 days

Work finished in 3 days

= 3/25 + 3/x = 1/5

=> x = 37(1/2) days - One 5 letter word is to be formed taking all letters – S, A, P, T and E. What is the probability that this the word formed will contain all vowels together?
5/78/151/52/53/8Option D

Total words that can be formed is 5! = 120

Take: S, P, T and AE So their arrangement = 4! * 2! = 48

Required probability = 48/120 = 2/5
