If x : y = 2 : 5 , then (5x + 3y) : (5x - y) = ?
Answer & explanation
Correct answer: option 2
Given x : y = 2 : 5
Then, (5x + 3y) : (5x - y) = (5 x 2 + 5 x 3) : (2 x 5 - 5)
= (25) : (5)
= 5 : 1
If x : y = 2 : 5 , then (5x + 3y) : (5x - y) = ?
Correct answer: option 2
Given x : y = 2 : 5
Then, (5x + 3y) : (5x - y) = (5 x 2 + 5 x 3) : (2 x 5 - 5)
= (25) : (5)
= 5 : 1
