Each of the followed paired numbers have a relationship that's the same for all of the paired numbers. What is the missing number?

{4, 100} {7, 111} {8, 1000} {1, 1} {12, 1100} {2, ?}

Each pair consist binary equivalent, so answer is 10

(8, 1000) (2^3, 10^3)

(4, 100)  (2^ 2, 10^2)

(1,1)( 2^0, 10^0)

(2,?)( 2^1, 10^1)

hence missing no should be 10

ans:  10
(each second no is binary equivalent of the 1st no)

This question could be solved by binary form (4,100) if 1*2^2+0*2^1+0*2^0==4

(12,1100) if 1*2^3+1*2^2+0*2^1+0*2^0

same as (2,?)=10 is the answer

1*2^1+0*2^0

It is binary relation...so for 2 it is 010

binaryyyyy......so itll be d binary f 2...

it is (2, 10) i.e. binary representation of 2

answer will be {2,10} as all the numbers are given in their binary equivalent..

answer is 10, binary no.of 2
