If x + y = 10, 2xy = 48 and x > y, then find 2x - y.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 8
Given that
If x + y = 10, 2xy = 48 and x > y
Put x = 6, y = 4
6 + 4 = 10 , 2 * 6 * 4= 48 and 6 > y
Hence value satisfies all the conditions given
Thus, the value of 2x - y = 2 * 6 - 4 = 12 - 4 = 8
