Question

Emily thought of a counting number, and then she added the next counting number to it. She got the sum of 57. What was Emily’s number?

Answer 1

Let this number be x. The next number is (x+1). And their sum is 57. Then, we have to solve this equation x+x+1=57
                                       $2x=56$
                                       $x=28$
Emily's number was 28
