Question

. Given that x and y are whole numbers such that x is less than y and xy = 2022 , write down all the possible pairs (x, y) .​

Answer 1

Answer:

Given:

• x and y are positive integers

• x + y = 2

To find:

• From the given options, which one could be the value of 300x + 200y

Approach and Working:

We can rewrite the given expression 300x + 200y in the following manner:

• 300x + 200y = 200x + 200y + 100x = 100x + 200 (x + y) = 100x + 200*2 = 100x + 400

Now, as x is positive, 100x > 0

• Hence, 400 + 100x > 400

Only one value is more than 400 (i.e. 533)
