Question

If one of two integers is 5% of the other, and their sum is 63, what is their product

Answer 1

180

Explanation:

Let x be the first integer.

Let y be the 2nd integer.

Given info from the question,

x = 5% x y

x = 0.05y - equation 1

x + y = 63 - equation 2

Lets now substitute equation 1 into equation 2.

0.05y + y = 63

1.05y = 63

y = 63 / 1.05

= 60

Now we substitute y into equation 1.

x = 0.05(60)

= 3

Now since we know both x and y,

we can find the product of them.

xy = 60 * 3 = 180
