WANT TO VERIFY MY ANSWER WITH OA

What is the value of x?
(1) When x is multiplied by 8, the result is between 50 and 60.
(2) When x is doubled, the result is between 10 and 15.

i think the no is 7 & answer is C but OA is diff.

i think you are assuming X has to be an INTEGER which from the question it doesnt have to be.

So 50/8 = ~6.3 and 60/8 =~7.5
Now when you double any of them they should be between 10 and 15... which basically mean the entire range.

5<x<7.5
6.25<x<7.5

x could be anything , even if we take A+B.
hence E
