(B) 200
(C) 120
(D) 40
(E) 20

Bunuel · Answer

2x = 10;
3y = 10;

Multiply: 6xy=100 --> 12xy=200.

Answer: B.

ScottTargetTestPrep · Answer

Since 2x = 10, x = 5. Since 3y = 10, y = 10/3. Thus

12xy = 12(5)(10/3) = 4(5)(10) = 200

Answer: B

KSBGC · Answer

it's given that 2x=3y=10. It means that the value of both 2x and 3y is 10.

we are asked to find out the value of 12xy = 3*2*2*x*y= 3y*2x*2=10*10*2=200

Thus the best answer is B.
