Question 60558
Given   (500-x)/y = 1.28-----------(1)
        (470-x)/y = 0.25 ----------(2)
Multiply both sides by y, we get
(500-x) = 1.28 y     ---------------(3)
(470 – x)  = 0.25 y  --------------(4)
Subtract the above equation, we get
30 = 1.03 y
(30 / 1.03) = y
29.12 = y
Substitute the value of “y” in the above equation, we get
500 - x = 1.28 * 29.12
500 –x = 37.28
 500 -37.28 = x 
462.71 = x
The value of x = 462.71 and y = 37.28
