Question


If 1.5x = 0.04y, then the value of ( (y-x) / (y+x) ) is :


A. 7.3/77
B. 730/77
C. 73/77
D. 7300/77


Answer: C. 73/77


Solution:

Given:
If 1.5x = 0.04y

Calculation:

If 1.5x = 0.04y

⇒ x/y = 0.04/1.5

⇒ x/y = (4 × 10)/(1.5 × 100)

⇒ x/y = 2/75

It means x = 2, and y = 75

((y – x) / (y + x))

⇒ (75 – 2)/(75 + 2)

⇒ 73/77

∴ The value of((y – x) / (y + x)) is 73/77.
