Q3 of 27 Page 97

The reciprocal of a positive number, subtracted from the number itself gives . What is the number?

Let the number be x


Then reciprocal of number is


If reciprocal number, subtracted from the number itself is 1


Then;


(x–) = = 1


∴ comparing both



x = 2


x2–1 = 3


x2 = 4


x = √4 = 2


∴ the number is 2


Conclusion/Result. Number comes out to be 2
