## 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.**
