    Hi,

    Following are the problems that seems to be wrong:

    Q. Lesson Name : Inequalities I and Qno. 9

    Answer should be 25, problem here is you got 25 in your solution but you wrote 5 as answer. Dont know why. also there seems to by typo error in solution : 5k - 51 > 25, it should be 5k - 5l > 25.

    Q. Lessons name: Inequalities I and Qno. 10:

    Answer should be D, as 0<x means x is greater than zero, which mean x is positive. in your solution x you have consider x as negative.

    Q1) Lesson Name: inequalities II and question no 1.

    Your explanation does not consider mod given in that question. and possible values of x is x< -2 & |x| > 2. which implies Answer A is correct.
