Question

If x:y =4:7 and the difference between x and y is 12, what are the values of x and y

Answer 1

Let the values of x and y be 4x and 7x
Given, the difference between x and y is 12
therefore,
7x -4x =12
x = 4
then, value of x = 4x= 4×4=16
value of y = 7x= 7×4=28
therefore the values of x and y are 16 and 28
