1. If an integer y is subtracted from an integer x, and the result is greater than x, then y must be ---
- A. Equal to x
- B. Equal to x
- C. Equal to x
- D. Equal to x
Answer: Option B
Explanation:
x - y > x
x = 1 এবং y = - 1 হলে, x - y = 1 - ( - 1) = 2>1
x = 1 এবং y = - 2 হলে, x - y = 1 + 2 = 3 >1
y <0 হলে x - y > x শর্তটি সিদ্ধ হয়।
