The number of red bricks/The number of gray bricks was 5/2. There were 175 bricks used in all. How many red bricks were used?

125

50

35

Verified Answer :

lets say 
Red bricks = 5x 
Gray bricks = 2x 

5x + 2x = 175 
7x = 175 
x = 175/7 
x = 25 

Red bricks =(5x) = 5 25 = 125 
Gray bricks =(2x) = 2 25 = 50
