Question:
By observing the given number line, find which of the following will have the greatest value?
(A) a + b
(B) b - a
(C) a x b
(D) a = b
[See image attached]
Answer:
(B) b - a is the correct answer.
Step-by-step explanation:
On the left side of 0 there will be negative integers. In image, a is a negative integer.
On the right side of 0 there will be positive integers. In image, b is a positive integer.
(A) a + b
Applying signs
-a + b
This will give result in positive or negative integer.
(B) b - a
Applying signs
b - (-a)
b + a
This will give result in positive integer.
(C) a x b
Applying signs
-a x b
This will give result in negative integer.
(D) a = b
Applying signs
-a ≠ b
Positive integer and Negative integer can't be equal.
From all options (B) b - a will have greatest value as in other options either we are getting negative value or we are not sure that result will be positive or negative.
Answer:
Answers is b-a
