(A) 44km
(B) 40km

48. The sum of two numbers is equal to 20 and their difference is 25. The ratio of the two numbers is.
(A) 9:1
(B) 3:1
(C) 4:1
(D) 4:5
Answer:
(A) 9:1
Explanation:
Let the numbers be x and y. x+y=20 and x−y=25. Adding the equations yields 2x=45 x=22.5. Subtracting them yields 2y=−5 y=−2.5. The ratio of their absolute values is 22.5:2.5, which simplifies to 9:1.
