P = {x : x, 12 এর গুণনীয়ক সমূহ} এবং Q = {x : x, 3 গুণিতক এবং (x≤12) হলে (P - Q) = কত?
Solution
Correct Answer: Option A
P = {x : x, 12 এর গুণনীয়কসমূহ}
∴P= {1,2,3,4,6,12}
এবং Q = {x : x, 3 এর গুণিতক এবং x≤ 12}
∴Q = {3,6,9,12}
এখন, P - Q = {1,2,3,4,6, 12} - {3,6,9,12} = {1,2,4}
∴P= {1,2,3,4,6,12}
এবং Q = {x : x, 3 এর গুণিতক এবং x≤ 12}
∴Q = {3,6,9,12}
এখন, P - Q = {1,2,3,4,6, 12} - {3,6,9,12} = {1,2,4}
