Explanation

Begin by Plugging In 7 for y, so 20 percent of x is 35. You could go on to solve for x, but a shortcut would be to say that 60 percent of x is three times 20 percent of x, so multiply 35 by 3 to get 105.


Hence option A is correct.

If 20% of x = 5y, then...
40% of x = 10y
and 60% of x = 15y

Since y = 7, then 15y = (15)(7) = 105

Answer: A

20 percent of x is 5y, and y = 7

so x= 175
Now 60% of 175 = 105
