The rule is:
sqaure root of ( square of x ) can be +x or -x as (+x) *(+x) = (-x)(-x).
In this case x<0, hence we take -x.

|------(0,0)-------| A | (B) |<---- Say 'x' | (c) From (0,0) to (b) is 4. From (0,0) to (c), center of circle is x. Hence by Pythagoras Theorem :) r^2 = x^2 + 4^2 For maximum value of (r), x^2 + 14 should be maximum. And there is NO limit for a maximum number or even a perfect square no. Ans is (E)....

Taking Stmt (1) alone, r < 4 can have Prime numbers infinite, ( considering -ve int also ) Taking Stmt(2) alone, No Clue for "r" Taking Both (1) and (2), q=18, and r < 4, q = 2x3x3. clue is it asks if "q is a multiple of r" and Not the value of "r". Hence Both Stmt are ...

The approach to such problems would be for a sequence of numbers or if you are brilliant, recall a function that satisfies the condition. I prefer the former one. a(1) = 1; a(2) = -1; a(3) = 3 ; a(4) = -3 ; a(5) = 5; a(6) = -5 a(-1) = -1; a(-2)= -a(-3)..hence undefined Also "0" is Neither ...

If you start from (B), x < 0 implies |x| = (-x), y & z does not come into picture. So we have to take stmt A. from A alone we have x = -(y - z ). Combining (A) and (B) x = (y -z ) and principle of modulus states, |x| = a implies -a <= x < a in this case 'a' being ( y - z ). Hence Both stmts are ...

Total number of ways two workers out of 6 can be choosen is C(6,2) = 6x5/2 = 15.
Favourable case i.e. instance(s) in which JJ's will be choosen is Only One. As for a pair of JJ, it can happen once in all combinations.
hence reqd probability is 1/15.
