If (A-B)= 3 5 and A B=2 , then

Options

  1. AA B= 1 5
  2. BA B=- 1 5
  3. CA B=- 1 5
  4. DA B= 1 5

Correct answer

A. A B= 1 5

Step-by-step solution

Given (A-B) = A B + A B = 3 5 . Also given A B = 2 , which implies A B A B = 2 , so A B = 2 A B . Substituting this into the first equation: A B + 2 A B = 3 5 3 A B = 3 5 A B = 1 5 . Now, using A B = 2 A B : A B = 2 1 5 = 2 5 . Answer: A B= 1 5
