Question

1=11,2=22,3=33,5=55,6=66,11=?

Answer 1

The following is given in the form of a sequence. One can also write this in the form of an Arithmetic Progression.

The next number in the sequence is 121 when it is considered as an Arithmetic Progression, while the number can be written as 111 when it is considered as a patterned sequence as the number repeats itself in all the given cases.

Another way it can be solved is that it can also be written as 1 because the first step mentions that 1=11.

 So, we can have three options for the answer: 121 or 111 or 1.

Answer 2

Method 1
1 * 11 = 11
2 * 11 = 22
3 * 11 = 33
4 * 11 = 44
5 * 11 = 55
6 * 11 = 66
So, similarly -
11 * 11 = 121

Method 2
By doubling the last digit, we have
1 = 11
2 = 22
3 = 33
4 = 44
5 = 55
6 = 66
And, 11 = 111 .

Conclusion : 111 & 121 both are correct answers. The correct answer depends upon the question pattern asked.
