Solution

Given:  
 • 20% of x = 5y
• y = 7

To find:  
 • The value of 60% of x =  \frac{60}{100} * x = \frac{3x}{5}

Approach and Working:  
As y = 7, 5y = 5 * 7 = 35

So, we can write:
 • 20% of x = 35
Or,  \frac{x}{5} = 35 
Or,  \frac{3x}{5} = 35 * 3 = 105

Hence, the correct answer is option A.

Answer: A

KSBGC · Answer

20% of x = 5y
20/100 of x = 35................................y=7
(1/5)x = 35
x = 35*5

we are asked to find out 60% of x.

(35*5)*60/100
=105

Thus the best answer is A.

Short-cut:

(35/20)*60
=105

mygmat0101 · Answer

answer is 105

x=25y=175

60% of 175 is 105

JeffTargetTestPrep · Answer

Since 20 percent of x is 5y and y = 7, we have:

0.2x = 5(7)

0.2x = 35

x = 175

So 60% of 175 is 0.6 x 175 = 105.

Answer: A

Abhishek009 · Answer

20  % =  \frac{1}{5}

So,  \frac{x}{5} = 5*7

Or,  x = 25*7

So,   60   %   of x  =  105 ,  Answer must be (A)

BrentGMATPrepNow · Answer

GIVEN:  20  percent of x =  5 y 
This means:  40  percent of x =  10 y 
And:  60  percent of x =  15 y

Since y =   7  , we can write:  60  percent of x =  15 (  7  ) = 105

Answer: A

If 20 percent of x is 5y, and y = 7, what is 60 percent of x?
