Multiple-choice question …

E) 0 is correct.

We must compare the given expression with square expressions.

Observe that c2 + 5c + 6 = (c + 2)(c + 3), and, since c is a positive

whole number,

(c + 2)

< (c + 2)(c + 3) < (c + 3)

This places it between two consecutive squares, hence c2+5c+6 can never

be a perfect square. There is no number of required form between 1 and

100: (D) is correct.

For those who are under Muda and Sulong Category, if you didn’t score well in the previous selection test, do not worry.

There will another test coming soon, and we will finalize the OMK team after the test.

I would probably set the paper similiar to Hua Lo-Keng Cup, which is in multiple-choice, with an additional choice of selecting “No answer” or “Cannot be determined using given information”. A penalty system will also be applied to the scoring for incorrect attempt. However, I will also include some structure question, but not many, don’t worry.

Before that, please try the posted problems and understand the solution. Good Luck !
