Question:

If x + y + z = 360 and x : y : z = 4 : 3 : 2, then what is the value of y + z − x?

Options:

Correct Answer:

Explanation:

If x + y + z = 360

x : y : z = 4 : 3 : 2,

then what is the value of y + z − x

Let the three numbers = 4m , 3m and 2m

according to he question,

4m + 3m + 2m = 360

9m = 360

m = 40

y + z − x = 40 × 3 + 40 × 2 - 40 × 4 = 200 - 160 = 40
