2) What is 12.25% of 2000?
Answer Is: (C) 245
Explanation:
12.25% of 2000 = (12.25/100 ) x 2000 = 245
3) In the given sequence, 3, 7, 13, k,31, 43. What should be the value of k?
4) What should come in place of X in the below number series?
83, 54, X , -4, -33
Answer Is: (B) 25
Explanation:
The given series is 83, 54, X , -4, -33
Consecutive numbers decreases by 29
Following this pattern, the Missing Number X should decrease by 29 from the previous number
When we subract 29 to the number before X (i.e 54)
we get 54 - 29 = 25
5) A and B can complete the work in 20 and 36 days respectively. A works for the first 5 days and then quits. How many days B has to work to complete the work ?

A 's 1 day work = 1/20 A's 5 day work = 5/20 = 1/4
B has to do the remaining 3/4 of the work B will take 36 x (3/4) days = 27 days
6) Find the Missing number in the the below series
107, 134, 161, X , 215, 242
Answer Is: (C) 188
Explanation:
The given series is 107, 134, 161, X , 215, 242
Consecutive numbers increases by 27
Following this pattern, the Missing Number X should increase by 27 from the previous number.
When we add 27 to the number before X
We get 161 + 27 = 188
8) What is 13.75% of 3500?
Answer Is: (C) 481.25

13.75% of 3500 = (13.75/100 ) x 3500 = 481.25
9) What number comes next : 899 , 960 , 1023 , 1088 , ... ?
Answer Is: (D) 1155
Explanation:
899 , 960 , 1023 , 1088
First number is 30 x 30 - 1 = 899
Second number is 31 x 31 - 1 = 960
Third number is 32 x 32 - 1 = 1023
Fourth number is 33 x 33 - 1 = 1088
Next number has to 34 x 34 - 1 = 1155
10) In the given series, can you find the Missing number?
70, 61, X , 43, 34
Answer Is: (A) 52
Explanation:
The given series is 70, 61, X , 43, 34
Consecutive numbers decreases by 9
Following this pattern, the Missing Number X should decrease by 9 from the previous number
When we subract 9 to the number before X
We get 61 - 9 =52
11) X,Y,Z complete a given work in 12 , 42 and 28 days respectively. If all three of them work together, in how many days the work will get completed ?
Answer Is: (D) 7 days
Explanation:
X's 1 day work = 1/12
Y's 1 day work = 1/42
Z's 1 day work = 1/28
All three are working together
X+Y+Z 's1 day work = (1/12) + (1/42) + (1/28)
[L C M of 12 , 42 , 28 = 84]
= (7 + 2 + 3) / 84 = 12 / 84
X+Y+Z 's 1 day work = 1/7
X+Y+Z will take 7 days to finish the work
Answer is 7
12) Hemal can complete a work in 8 days, what percentage of the work would be completed in 2 days ?
