All numbers/15 is an in integer excepr 85. So 85 must also be considered an answer.

105/15 = 7,

85/15 = 5.6,

60/15 = 4,

30/15 = 2,

0/15 = 0,

-45/15 = -3,

-90/16 = -9.

Find odd one out 105, 85, 60, 30, 0, -45, -90.

@B D Vekaria.

b) 50, 51, 47, 56, 42, 65, 29.

Answer is 42 because
+1, -4, +9, -16, +25, -36 ------> 1^2, 2^2, 3^2, 4^2, 5^2, 6^2.
But we are getting 1, -4, +9, -14.

105-85=20
85-60=25
60-30=30
30-0=30
0-(-45)=45
-45-(-90)=45
if we replace 0 by -5 we get sequence like 20 25 30 35 40 45. that's y 0 is wrong ans.. am i correct

105-85 = 20.
85-60 = 25.
60-30 = 30.
30-0 = 30.
0-(-45 )= 45.
-45-(-90) = 45.

If we replace 0 by -5 we get sequence such as 20, 25, 30, 35, 40, 45.

105-85 = 20.
85-60 = 25.
60-30 = 30.
30-0 = 30.
0-(-45 )= 45.
-45-(-90) = 45.

If we replace 0 by -5 we get sequence such as 20, 25, 30, 35, 40, 45.

According to the answer provided by Indiabix. If all are successive number then why minus sign is there before 45 and 90.

I think wrong question.

@D B Vekaria.

The wrong answer is 20.

3-1=2, 6-3=3, 1-61=5, 20-11=9, 9-20=11, 70-39=31.
2, 3, 5, 11, 31 are prime numbers except 9.

85 is also a probable answer to this question.

Because each of the given numbers in the series except 85 is divisible by 3.

Vinay said:   8 years ago
I agree @Bhavana.

We have to select the odd one out so yeah except 85 all others are divisible by 3 and 15.

Hi guys, all the numbers divisible by 5. So, 0 is the not divided by 5. 0 is the answer.
