Answer 1

Required integer is -12.

Explanation:

Given:

Required number is integer.

Required integer is less than zero

greater than -13.

When number is substracted from -11, result is positive.

To Find:

The integer=?

Solution:

Lets assume required integer = x

As Required integer is less than zero and greater than -13 ,

-13 < x < 0 ------(1)

Also when number is subtracted from -11, result is positive.

=> -11 – x > 0

=> -11 > x -------(2)

So form 1 and 2

-13 < x < -11 that is x is an integer which is less than -11 and greater than -13. There is only one integer between -13 and -11 that is -12.

Hence required integer is -12.
