In following questions, one term in number series is incorrect.

Find out the incorrect number

1, 5, 5, 9, 7, 11, 11, 15, 12, 17

Find out the incorrect number

1, 5, 5, 9, 7, 11, 11, 15, 12, 17

The given sequence is a combination of two series:

I. 1, 5, 7, 11, 12 and

II. 5, 9, 11, 15, 17

The pattern in both I and II is + 4, + 2, + 4, + 2.

So, 12 is wrong and must be replaced by (11 + 2) i.e. 13..

The ages of two friends Julie is twice older than Katie. However if the age of Julie before 20 years and that of Katie after 20 years then Katie age is twice then Julie. What is the age of julie?

let, Julie age = A and Katie age=B

given that

A/B = 2 / 1

A=2B

A - 2B = 0......equation 1

and also given that, A - 20 / B+ 20 = 1/2

2A -40 = B + 20

2A-B= 60.....equation 2

by solving watch equation

A = 40

so, julie is 40 years old

.
On dividing 2272 as well as 875 by 3-digit number N, we get the same remainder. The sum of the digits of N is:

Clearly, (2272 - 875) = 1397, is exactly divisible by N.

Now, 1397 = 11 x 127

The required 3-digit number is 127, the sum of whose digits is 10.

20, 20, 17, 17, 14, 14, 11, ?, ?

What numbers should come next?

This is a simple subtraction with repetition series.

It begins with 20, which is repeated, then 3 is subtracted, resulting in 17, which is repeated, and so on.

Rule = (1st no.), (1st no.), (1st no. - 3 = 2nd no.), (2nd no. repeat), (2nd no. - 3 = 3rd no.), (3rd no. repeat)...

Now in our case, (20), (20), (20 - 3 = 17), (17), (17 - 3 = 14), (14), (14 - 3 = 11), (11), (11 - 3 = 8), (8)...

So the answer is c = 11, 8..
