ALGEBRA QUESTION OF THE DAY
If two non-zero positive integers p and q are such that p = 4q and p < 8, then q = (A) 1 (B) 2 (C) 3 (D) 4 (E) 5
Dividing both sides of the equation p = 4q by 4, we get q = p/4. We are also given that p < 8. Dividing both sides of this inequality by 4 yields, p/4 < 8/4. Simplifying it, we get p/4 < 2. But q = p/4. Hence, q < 2. The only non-zero positive integer less than 2 is 1. Hence, q = 1. The answer is (A).
