Correction in num properties guide;chapter11 prob set ques 1

[tom.tharakan]

There seems to be a small error in the explanation of question 1 in the problem set of chapter 11 in manhattan number properties guide .

Scenario 3 in the explanation of statement 1 has p, q, r as even, odd and even. But pq + r for 3rd scenario is wrongly computed as E * O + O = O instead of E * O + E = E.

However towards the end of the problem explanation it is mentioned, Scenario 8 of statement 2 and scenario 3 of statement 1 are the same, there by not causing a wrong answer.

Scenario 8 of statement 2 correctly shows pq+r as E * O + E = E.
However, calculation of pq + r in scenario 3 of statement 1 is wrong.

It has to be corrected, I believe..

Also:

Scenario 4 should say E * E + E = E (not O * E + E = E)

[tom.tharakan]

You are right. Scenario 4 is also written wrong. I didnt notice it previously.
