If 0 ≤ x ≤ 4 and y < 6, which of the following cannot be the value of xy?
Solution
Correct Answer: Option D
y < 6 হলে y এর মান 5, 4, 3, 2, 1, 0, - 1,..............
0 ≤ x ≤ 4 হলে x এর মান 0, 1, 2, 3, 4
এখন
x = 0, y = 1 হলে xy = 0 × 1 = 0
x = 2, y = - 1 হলে xy = 2 × (- 1) = - 2
x = 3, y = 2 হলে xy = 3 × 2 = 6
সঠিক উত্তর: None of these
