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.
