Practice Questions on Odd Man Out and Series
Find the odd man out from the following Questions :
Q 1. 1, 5, 15, 24, 29, 35, ?
a. 15
b. 24
c. 29
d. 35
Solution :
Out of all the numbers from the series, 24 is the only even number so option (b) will be the correct choice.
Q 2. 2, 4, 6, 10, 12, 15, 18, 20, 22 ?
a. 15
b. 10
c. 4
d. 20
Solution :
Out of all the numbers from the series, 15 is the only odd number so option (a) will be the correct choice.
Q 3. 1, 8, 27, 64, 81, 125, ?
a. 27
b. 64
c. 81
d. 125
Solution :
As we can observe except 81 all the numbers form a series of perfect cubes. Hence option (c) will be the correct choice.
Q 4. 1, 4, 9, 16, 25, 36, 49, 65, 81, 100.
a. 25
b. 36
c. 49
d. 65
Solution :
As we can observe except 65 all are perfect squares.
Q 5. 5, 10, 15, 20, 24, 30, 35, 40.
a. 15
b. 24
c. 30
d. 40
Solution :
As we can see all the numbers are a multiple of 5 except 24. Hence option (b) will be the correct choice.
Q 6. 4, 8, 12, 16, 20, 25, 28, 32, 36, 40.
a. 16
b. 20
c. 25
d. 28
Solution :
As we can see all the numbers are a multiple of 4 except 25. Hence option (c) will be the correct choice.
Q 7. 10, 27, 44, 61, 78, 95, 111, 129.
a. 111
b. 78
c. 95
d. 129
Solution :
As we can see from the series it’s an AP series of common differences 17. So out of all the numbers, 111 is the odd man out here. Hence option (a) will be the correct choice.
Q 8. 2, 4, 8, 16, 32, 64, 129, 256.
a. 64
b. 129
c. 256
d. 16
Solution :
As we can it’s a GP of common difference 2. Out of all the numbers, 129 will be the odd man out here. Hence option (b) will be the correct choice.
Q 9. 15, 19, 23, 27, 31, 35, 40. 43.
a. 23
b. 27
c. 35
d. 40
Solution :
We can answer this by using two methods –
1 – 40 is the only even number so 40 will be the odd man out here.
2 – As we can observe it is an AP of common difference 4. So 40 is not the next term after 35. Hence option (d) will be the correct choice.
Q 10. 4, 12, 36, 108, 325, 972.
a. 36
b. 325
c. 108
d. 972
Solution :
As we can see this is a GP of common difference 4. 325 will be the odd man out here. Hence option (b) will be the correct choice.
